DYE MIXTURES OF FIBER-REACTIVE AZO DYES, THEIR PREPARATION AND THEIR USE The invention relates to the technical field of fiber-reactive azo dyes. Fiber-reactive azo dye mixtures and their use for dyeing hydroxyl- and/or carboxamido-containing material in orange to red hues are known for example from the documents EP 0 681 007, EP 1 013 729, EP 0 957 137 and EP 0 719 841. However, these have certain performance defects, for example an excessive dependence of the color yield on changing dyeing parameters in the dyeing operation, or an insufficient or unlevel color buildup on cotton (good color buildup follows from the ability of a dye to produce the correspondingly stronger dyeing from an increased concentration of dye in the dyebath). Possible consequences of these defects are for example poor reproducibilities for the dyeings which are obtainable, which ultimately compromises the economics of the dyeing operation. Consequently, there continues to be a demand for novel reactive dyes or reactive dye mixtures having improved properties, such as high substantivity combined with good washoff for unfixed portions. They shall moreover also provide good dyeing yields and possess high reactivity and they shall more particularly provide dyeings having high degrees of fixation. The present invention, then, provides dye mixtures which possess these above- described properties to a high degree. The novel dye mixtures are notable in particular for high yields of fixation and ready washoff for portions not fixed on the fiber. In addition, the dyeings exhibit good general fastnesses, such as for example high lightfastness and very good wetfastnesses, and also have a low tendency to stain polyamide in the case of cotton-polyamide blend fabrics. The invention accordingly provides dye mixtures which comprise one or more, such as two or three, preferably 1 or 2, dyes of the hereinbelow indicated and defined general formula (I) and one or more, such as two or three, preferably 1 or 2, dyes of the hereinbelow indicated and defined general formula (II) and also optionally one or more, such as two or three, preferably 1 or 2, dyes of the hereinbelow indicated and defined general formulae (Ga) to (Gf) where D1 to D3 and D5 to D9 are independently a group of the general formula (1) where R1 and R2 are independently hydrogen, (C1-C4)-alkyl, (C1-C4)-alkoxy, hydroxyl, sulfo, carboxyl, cyano, nitro, amido, ureido or halogen;

For example, when the diazo components having the groups D2 and D3 and, if appropriate, D4 and optionally D7 as per the general formulae (I) and (II) and, if appropriate, (100) and (Gb) have the same meaning, it is possible for an amine of the general formula (17) D2-NH2 (17), where D2 is as defined above, to be diazotized in a conventional manner and the diazonium compound obtained being subsequently reacted with an aqueous solution or suspension of a mixture having a fixed ratio of a monoazo dye as per the general formula (15) and of at least one coupler as per the general formula (18) and optionally of a monoazo dye as per the general formula (19) where D1, D6, R*, R**, R°, R32, T, b, f, v and M are each as defined above. Alternatively, the dye mixture according to the present invention can be prepared when the groups D1, D2 and D3 and, if appropriate, D4 and optionally D6, D7 as per the general formulae (I) and (II) and, if appropriate, (100) and (Gb) have the same meaning, which comprises an amine of the general formula (20) D1-NH2 (20), where D1 is as defined above, being diazotized in a conventional manner and coupled onto a mixture of in each case at least one coupling component (21) and (15) and also optionally (22) where R*, R**, R°, R32, T, b, f, v and M are each as defined above, firstly at a pH below 3 in a first stage and subsequently further coupled by an increase in pH to form a mixture of the dyes of the general formulae (I) and (II) and optionally (Gb). The dye mixture according to the present invention is isolated in a conventional manner by salting out for example with sodium chloride or potassium chloride or by spray drying or evaporation. Similarly, the solutions produced in the course of the synthesis of the dyes of the general formula (I) and (II) and optionally (Ga) to (Gf) can be used directly as liquid products in dyeing, if appropriate after addition of a buffer substance and if appropriate after concentrating. Dye mixtures which as well as b-chloroethylsulfonyl or (i-thiosulfatoethylsulfonyl or b-sulfatoethylsulfonyl groups also contain vinylsulfonyl groups as reactive radicals can be synthesized not only starting from appropriately substituted vinylsulfonyl- anilines or naphthylamines but also by reaction of a dye mixture where Z is ß-chloroethyl, ß-thiosulfatoethyl or ß-sulfatoethyl with an amount of alkali required for the desired fraction and converting the ß-substituted ethylsulfonyl groups mentioned into vinylsulfonyl groups. This conversion is effected in a manner familiar to one skilled in the art. The dye mixtures according to the invention have useful application properties. They are used for dyeing or printing hydroxyl- and/or carboxamido-containing materials, for example in the form of sheetlike structures, such as paper and leather or of films, for example composed of polyamide, or in bulk, such as for example polyamide and pOlyurethane, but especially for dyeing and printing these materials in fiber form. Similarly, the as-synthesized solutions of the dye mixtures according to the invention can be used directly as a liquid preparation for dyeing, if appropriate after addition of a buffer substance and if appropriate after concentration or dilution. The present invention thus also provides for the use of the dye mixtures according to the invention for dyeing or printing these materials, or rather processes for dyeing or printing these materials in a conventional manner, by using a dye mixture according to the invention or its individual components (dyes) individually together as a colorant. The materials are preferably employed in the form of fiber materials, especially in the form of textile fibers, such as woven fabrics or yarns, as in the form of hanks or wound packages. Hydroxyl-containing materials are those of natural or synthetic origin, for example cellulose fiber materials or their regenerated products and polyvinyl alcohols. Cellulose fiber materials are preferably cotton, but also other vegetable fibers, such as linen, hemp, jute and ramie fibers; regenerated cellulose fibers are for example staple viscose and filament viscose and also chemically modified cellulose fibers, such as aminated cellulose fibers or fibers as described for example in WO 96/37641 and WO 96/37642 and also in EP-A-0 538 785 and EP-A-0 692 559. Carboxamido-containing materials are for example synthetic and natural polyamides and polyurethanes, especially in the form of fibers, for example wool and other animal hairs, silk, leather, nylon-6,6, nyIon-6, nylon-11 and nylon-4. The dye mixtures according to the invention can be applied to and fixed on the substrates mentioned, especially the fiber materials mentioned, by the application techniques known for water-soluble dyes and especially for fiber-reactive dyes. For instance, on cellulose fibers they produce by the exhaust method from a long liquor and also from a short liquor, for example in a liquor to goods ratio of 5 : 1 to 100 :1, preferably 6 : 1 to 30 :1, using various acid-binding agents and optionally neutral salts as far as necessary, such as sodium chloride or sodium sulfate, dyeings having very good color yields. Application is preferably from an aqueous bath at temperatures between 40 and 105°C, optionally at a temperature of up to 130°C under superatmospheric pressure, but preferably at 30 to 95°C, especially 45 to 65°C, in the presence or absence of customary dyeing auxiliaries. One possible procedure here is to introduce the material into the warm bath and to gradually heat the bath to the desired dyeing temperature and complete the dyeing process at that temperature. The neutral salts which accelerate the exhaustion of the dyes may also if desired only be added to the bath after the actual dyeing temperature has been reached. Padding processes likewise provide excellent color yields and a very good color buildup on cellulose fibers, the dyes being fixable in a conventional manner by batching at room temperature or elevated temperature, for example at up to 60°C, or in a continuous manner, for example by means of a pad-dry-pad steam process, by steaming or using dry heat. Similarly, the customary printing processes for cellulose fibers, which can be carried out in one step, for example by printing with a print paste containing sodium bicarbonate or some other acid-binding agent and by subsequent steaming at 100 to 103°C, or in two steps, for example by printing with a neutral to weak acidic print color and then fixing either by passing the printed material through a hot electrolyte- containing alkaline bath or by overpadding with an alkaline electrolyte-containing padding liquor and subsequent batching or steaming or dry heat treatment of the alkali-overpadded material, produce strong color prints with well-defined contours and a clear white ground. The outcome of the prints is affected little, if at all, by variations in the fixing conditions. When fixing by means of dry heat in accordance with the customary thermofix processes, hot air at 120 to 200°C is used. In addition to the customary steam at 101 to 103°C, it is also possible to use superheated steam and high-pressure steam at temperatures of up to 160°C. The acid-binding agents which effect the fixation of the dyes of the dye mixtures according to the invention on the cellulose fibers are for example water-soluble basic salts of alkali metals and likewise alkaline earth metals of inorganic or organic acids or compounds which liberate alkali in the heat, and also alkali metal silicates. Especially suitable are the alkali metal hydroxides and alkali metal salts of weak to medium inorganic or organic acids, the preferred alkali metal compounds being the sodium and potassium compounds. Such acid-binding agents are for example sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, potassium carbonate, sodium formate, sodium dihydrogenphosphate, disodium hydrogenphosphate, sodium trichloroacetate, trisodium phosphate or waterglass or mixtures thereof, for example mixtures of aqueous sodium hydroxide solution and waterglass. The present invention further relates to the use of the dye mixtures of the present invention in printing inks for digital textile printing by the inkjet process. The printing inks of the present invention comprise the reactive dye mixtures of the present invention, for example in amounts from 0.1 % by weight to 50% by weight, preferably in amounts from 1 % by weight to 30% by weight and more preferably in amounts from 1 % by weight to 15% by weight based on the total weight of the ink. They may also include combinations of the aforementioned reactive dye mixtures with other reactive dyes used in textile printing. For the inks to be used in the continuous flow process, a conductivity of 0.5 to 25 mS/m can be set by adding an electrolyte. Useful electrolytes include for example lithium nitrate and potassium nitrate. The dye inks of the present invention may include organic solvents at a total level of 1-50% and preferably 5-30% by weight. Suitable organic solvents are for example alcohols, for example methanol, ethanol, 1-propanol, isopropanol, 1-butanol, tert-butanol, pentyl alcohol, polyhydric alcohols for example: 1,2-ethanediol, 1,2,3- propanetriol, butanediol, 1,3-butanediol, 1,4-butanediol, 1,2-propanediol, 2,3- propanediol, pentanediol, 1,4-pentanediol, 1,5-pentanediol, hexanediol, D,L-1,2- hexanediol, 1,6-hexanediol, 1,2,6-hexanetriol, 1,2-octanediol, polyalkylene glycols, for example: polyethylene glycol, polypropylene glycol, alkylene glycols having 2 to 8 alkylene groups, for example monoethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, thioglycol, thiodiglycol, butyltriglycol, hexylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, low alkyl ethers of polyhydric alcohols, for example: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, diethylene glycof monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, diethylene glycol monohexyl ether, triethylene glycol monomethyl ether, triethylene glycol monobutyl ether, tripropylene glycol monomethyl ether, tetraethylene glycol monomethyl ether, tetraethylene glycol monobutyl ether, tetraethylene glycol dimethyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monobutyl ether, tripropylene glycol isopropyl ether, polyalkylene glycol ethers, such as for example: polyethylene glycol monomethyl ether, polypropylene glycol glycerol ether, polyethylene glycol tridecyl ether, polyethylene glycol nonylphenyl ether, amines, such as, for example: methylamine, ethylamine, triethylamine, diethylamine, dimethylamine, trimethylamine, dibutylamine, diethanolamine, triethanolamine, N-acetylethanolamine, N-formylethanolamine, ethylenediamine, urea derivatives, such as for example: urea, thiourea, N-methylurea, N,N'- dimethylurea, ethyleneurea, 1,1,3,3-tetramethylurea, amides, such as for example: dimethylformamide, dimethylacetamide, acetamide, ketones or keto alcohols, such as for example: acetone, diacetone alcohol, cyclic ethers, such as for example; tetrahydrofuran, trimethylolethane, trimethylolpropane, 2-butoxyethanol, benzyl alcohol, 2-butoxyethanol, gamma butyrolactone, epsilon-caprolactam, further sulfolane, dimethylsulfolane, methylsulfolane, 2,4-dimethylsulfolane, dimethyl sulfone, butadiene sulfone, dimethyl sulfoxide, dibutyl sulfoxide, N-cyclohexylpyrrolidone, N-methyl-2-pyrrolidone, N-ethylpyrrolidone, 2-pyrrolidone, 1-(2-hydroxyethyl)-2-pyrrolidone, 1-(3-hydroxypropyl)-2-pyrrolidone, 1,3-dimethyl- 2-imidazoIidinone, 1,3-dimethyl-2-imidazolinone, 1,3-bismethoxymethylimidazolidine, 2-(2-methoxyethoxy)ethanol, 2-(2-ethoxyethoxy)ethanol, 2-(2-butoxyethoxy)ethanol, 2-(2-propoxyethoxy)ethanol, pyridine, piperidine, butyrolactone, trimethylpropane, 1,2-dimethoxypropane, dioxane, ethyl acetate, ethylenediaminetetraacetate, ethyl pentyl ether. The printing inks of the invention may further include customary additives, for example viscosity moderators to set viscosities in the range from 1.5 to 40.0 mPas in a temperature range from 20 to 50°C. Preferred inks have a viscosity of 1.5 to 20 mPas and particularly preferred inks have a viscosity of 1.5 to 15 mPas. Useful viscosity moderators include Theological additives, for example: polyvTnylcaprolactam, polyvinylpyrrolidone and their copolymers polyetherpolyol, associative thickeners, polyurea, polyurethane, sodium alginates, modified galactomannans, polyetherurea, polyurethane, nonionic cellulose ethers. As further additives the inks of the invention may include surface-active substances to set surface tensions of 20 to 65 mN/m, which are adapted if necessary as a function of the process used (thermal or piezotechnology). Useful surface-active substances include for example: all surfactants, preferably nonionic surfactants, butyldiglycol, 1,2-hexanediol. The inks may further include customary additives, for example substances to inhibit fungal and bacterial growth in amounts from 0.01 to 1 % by weight based on the total weight of the ink. The inks may be prepared in a conventional manner by mixing the components in water. The dye inks of the invention are useful in inkjet printing processes for printing a wide variety of pretreated materials, such as silk, leather, wool, polyamide fibers and polyurethanes, and especially cellulosic fiber materials of any kind. Such fiber materials are for example the natural cellulose fibers, such as cotton, linen and hemp, and also pulp and regenerated cellulose. The printing inks of the invention are also useful for printing pretreated hydroxyl- or amino-containing fibers present in blend fabrics, for example blends of cotton, silk, wool with polyester fibers or polyamide fibers. In contrast to conventional textile printing, where the printing ink already contains all the fixing chemicals and thickeners for a reactive dye, in inkjet printing the auxiliaries have to be applied to the textile substrate in a separate pretreatment step. The pretreatment of the textile substrate, for example cellulose and regenerated cellulose fibers and also silk and wool, is effected with an aqueous alkaline liquor prior to printing. To fix reactive dyes there is a need for alkali, for example sodium carbonate, sodium bicarbonate, sodium acetate, trisodium phosphate, sodium silicate, sodium hydroxide, alkali donors such as, for example, sodium chloroacetate, sodium formate, hydrotropic substances such as, for example, urea, reduction inhibitors, for example sodium nitrobenzenesulfonates, and also thickeners to prevent flowing of the motives when the printing ink is applied, for example sodium alginates, modified polyacrylates or highly etherified galactomannans. These pretreatment reagents are uniformly applied to the textile substrate in a defined amount using suitable applicators, for example using a 2- or 3-roll pad, contactless spraying technologies, by means of foam application or using appropriately adapted inkjet technologies, and subsequently dried. After printing, the textile fiber material is dried at 120 to 150°C and subsequently fixed. The fixing of the inkjet prints prepared with reactive dyes may be effected at room temperature or with saturated steam, with superheated steam, with hot air, with microwaves, with infrared radiation, with laser or electron beams or with other suitable energy transfer techniques. A distinction is made between one- and two-phase fixing processes: In one-phase fixing, the necessary fixing chemicals are already on the textile substrate. In two-phase fixing, this pretreatment is unnecessary. Fixing only requires alkali, which, following inkjet printing, is applied prior to the fixing process, without intermediate drying. There is no need for further additives such as urea or thickener. Fixing is followed by the print aftertreatment, which is the prerequisite for good fastnesses, high brilliance and an impeccable white ground. The dye mixtures according to the invention are notable for outstanding color strength when applied to the cellulose fiber materials by dyeing or printing in the presence of no or very small amounts of alkali or alkaline earth metal compounds. In these special cases, for instance, no electrolyte salt is required for a shallow depth of shade, not more than 5 g/l of electrolyte salt is required for a medium depth of shade and not more than 10 g/l of electrolyte salt is required for deep shades. According to the invention, a shallow depth of shade refers to the use of 2% by weight of dye based on the substrate to be dyed, a medium depth of shade refers to the use of 2 to 4% by weight of dye based on the substrate to be dyed and a deep shade refers to the use of 4 to 10% by weight of dye based on the substrate to be dyed. The dyeing and prints obtainable with the dye mixtures according to the invention possess bright shades; more particularly, the dyeings and prints on cellulose fiber materials possess good lightfastness and especially good wetfastnesses, such as fastness to washing, milling, water, seawater, crossdyeing and acidic and alkaline perspiration, also good fastness to pleating, hotpressing and rubbing. Furthermore, the cellulose dyeings obtained following the customary aftertreatment of rinsing to remove unfixed dye portions exhibit excellent wetfastnesses, in particular since unfixed dye portions are easily washed off because of their good solubility in cold water. Furthermore, the dye mixtures according to the invention can also be used for the fiber-reactive dyeing of wool. Moreover, wool which has been given a nonfelting or low-felting finish (cf. for example H. Rath, Lehrbuch der Textilchemie, Springer- Verlag, 3rd edition (1972), pages 295-299, especially finished by the Hercosett process (page 298); J. Soc. Dyers and Colorists 1972, 93-99, and 1975, 33-44), can be dyed to very good fastness properties. The process of dyeing on wool is here carried out in a conventional manner from an acidic medium. For instance, acetic acid and/or ammonium sulfate or acetic acid and ammonium acetate or sodium acetate can be added to the dyebath to obtain the desired pH. To obtain a dyeing of acceptable levelness, it is advisable to add a customary leveling agent, for example a leveling agent based on a reaction product of cyanuric chloride with three times the molar amount of an aminobenzenesulfonic acid and/or of an aminonaphthalenesulfonic acid or on the basis of a reaction product of for example stearylamine with ethylene oxide. For instance, the dye mixture according to the invention is preferably subjected to the exhaust process initially from an acidic dyebath having a pH of about 3.5 to 5.5 under pH control and the pH is then, toward the end of the dyeing time, shifted into the neutral and optionally weakly alkaline range up to a pH of 8.5 to bring about, especially for very deep dyeings, the full reactive bond between the dyes of the dye mixtures according to the invention and the fiber. At the same time, the dye portion not reactively bound is removed. The procedure described herein also applies to the production of dyeings on fiber materials composed of other natural polyamides or of synthetic polyamides and polyurethanes. In general, the material to be dyed is introduced into the bath at a temperature of about 40QC, agitated therein for some time, the dyebath is then adjusted to the desired weakly acidic, preferably weakly acetic acid, pH and the actual dyeing is carried out at a temperature between 60 and 98°C. However, the dyeings can also be carried out at the boil or in sealed dyeing apparatus at temperatures of up to 106°C. Since the water solubility of the dye mixtures according to the invention is very good, they can also be used with advantage in customary continuous dyeing processes. The color strength of the dye mixtures according to the invention is very high. The dye mixtures according to the invention dye the materials mentioned, preferably fiber materials, in orange to red shades having very good fastness properties. The examples hereinbelow serve to illustrate the invention. Parts and percentages are by weight, unless otherwise stated. Parts by weight relate to parts by volume as the kilogram relative to the liter. The compounds described in the examples in terms of a formula are indicated in the form of the sodium salts, since they are generally prepared and isolated in the form of their salts, preferably sodium or potassium salts, and used for dyeing in the form of their salts. The starting compounds described in the examples hereinbelow, especially the table examples, can be used in the synthesis in the form of the free acid or likewise in the form of their salts, preferably alkali metal salts, such as sodium or potassium salts. Example 1 30 parts of an electrolyte-containing dye powder which contains the scarlet disazo dye of formula (1-1) in a 75% fraction and 70 parts of an electrolyte-containing dye powder containing the red azo dye of the formula (II-1) in a 70% fraction are mechanically mixed with each other. The resulting dye mixture according to the present invention provides red dyeings and prints on cotton for example under the dyeing conditions customary for reactive dyes. Example 2 40 parts of an electrolyte-containing dye powder containing the red disazo dye of the formula (I-2) in a 75% fraction and 60 parts of an electrolyte-containing dye powder containing the red disazo dye of the formula (II-100) in a 70% fraction are dissolved in 500 parts of water and the resulting dye solution is adjusted to pH 5.5-6.5. Evaporating this dye solution gives a dye mixture which provides red dyeings and prints on cotton under the dyeing conditions customary for reactive dyes. Example 3 281 parts of 4-(b--sulfatoethyIsulfonyl)aniline are suspended in 700 parts of ice-water and 180 parts of 30% hydrochloric acid and diazotized by dropwise addition of 173 parts of 40% sodium nitrite solution. After excess nitrite had been removed with sulfamic acid solution, the diazo suspension obtained is pumped into an aqueous solution of 397 parts of the scarlet monoazo dye of the formula (15-1) which was obtained by diazotization of 180.5 parts of 2-amino-5-(b-sulfatoethyl- sulfonyl)benzenesulfonic acid with 87 parts of 40% sodium nitrite solution in an acidic medium and subsequent coupling onto 166.5 parts of 4-hydroxy- 7-(sulfomethylamino)naphthalene-2-sulfonic acid at pH 1.5.140.5 parts of 7-acetylamino-4-hydroxynaphthalene-2-sulfonic acid are subsequently added as a second coupling component and pH 5 - 6 is set at below 25°C and maintained with sodium carbonate. The 65 : 35 mixture of the two dyes (I-3) and (II-2) which is formed after the coupling reaction has ended can be isolated by evaporation under reduced pressure or by spray drying; alternatively, the dye solution obtained can also be buffered at pH 5.5 - 6 by addition of a phosphate buffer and be further diluted or concentrated to provide a liquid brand of defined strength. The dye mixture obtained according to the present invention dyes cotton in reddish orange shades. Example 4 422 parts of 4-(b-sulfatoethylsulfonyl)aniline are suspended in 1000 parts of ice- water and 270 parts of 30% hydrochloric acid and diazotized by dropwise addition of 260 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid solution, the diazo suspension obtained is admixed with an aqueous solution of 166.5 parts of 4-hydroxy-7-(sulfomethylamino)naphthalene-2-sulfonic acid (obtained by reaction of 119.5 parts of 7-amino-4-hydroxynaphthalene-2-sulfonic acid with 75 parts of formaldehyde sodium bisulfite in an aqueous medium at pH 5.5 - 6 and 45°C) and adjusted to pH 1.5 with solid sodium bicarbonate. After the acidic coupling has ended, this reaction mixture has added to it an aqueous solution of 335 parts of the second coupling component (18-1) and is adjusted to and maintained at pH 5 - 6 with sodium carbonate below 25°C. The 50 : 50 mixture of the two dyes (I-4) and (II-3) which has formed after the coupling reaction has ended can be isolated by evaporation under reduced pressure or by spray drying. The resulting dye mixture according to the present invention dyes cotton in red shades. Example 5 A binary mixture prepared similarly to the procedure described in example 3 from 554 parts of the scarlet disazo dye of the formula (I-3) and 277 parts of the red dye of the formula (II-4) is admixed with 277 parts of the red disazo dye of the formula (II-100), adjusted to a pH of 5.5 - 6.5 and isolated by evaporation of the aqueous solution. The resulting 50 : 25 : 25 mixture of the three dyes (I-3), (II-4) and (11-100) which is according to the present invention dyes cotton in red shades. Example 6 25 parts of an electrolyte-containing dye powder containing the red disazo dye of the formula (I-5) in a 75% fraction and 75 parts of an electrolyte-containing 1:1 dye mixture containing the two red azo dyes of the formulae (H-3) and (II-4) in a 70% fraction are mechanically mixed with each other. The resulting dye mixture according to the present invention provides red dyeings and prints on cotton for example under the dyeing conditions customary for reactive dyes. Example 7 a) 312 parts of 2-(b-sulfatoethylsulfonyl)aniline are suspended in 800 parts of ice- water by addition of 165 parts of concentrated sulfuric acid and diazotized by dropwise addition of 195 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid, a mixture of 250 parts of 4-hydroxy-7-(sulfomethyl- amino)naphthalene-2-sulfonic acid and 120 parts of 4-hydroxy-6-(sulfomethyl- amino)naphthalene-2-sulfonic acid (prepared by reaction of 179 parts of 7-amino- 4-hydroxynaphthalene-2-sulfonic acid and 86 parts of 6-amino-4-hydroxy- naphthalene-2-sulfonic acid with 171 parts of formaldehyde sodium bisulfite in an aqueous medium at pH 5.5 - 6 and 45°C) is added and coupled in a first stage at pH 1 to 2 below 20°C to form a mixture of two monoazo dyes as per the formulae (15-2) and (II-5). The stated pH range is set (and maintained during the coupling reaction) by addition of solid sodium bicarbonate. b) Separately, 211 parts of 4-(b-sulfatoethylsulfonyl)aniline are suspended in 520 parts of ice-water and 137 parts of 30% hydrochloric acid and diazotized by dropwise addition of 132 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid, this diazo suspension is added dropwise to the mixture of the first coupling stage from a) and pH 5.5 - 6.5 is set at below 25°C with sodium carbonate. The 3 : 1 mixture of the two azo dyes (I-6) and (II-5) which has formed after the second coupling reaction has ended is subsequently isolated by spray drying. The resulting dye mixture according to the present invention dyes cotton in brownish red shades. Example 8 25 parts of an electrolyte-containing dye powder containing the brownish red disazo dye in the formula (I-7) in a 75% fraction, 35 parts of an electrolyte-containing dye powder containing the red disazo dye of the formula (II-1) again in a 75% fraction and 40 parts of an electrolyte- containing dye powder containing the red disazo dye of the formula (II—3) in a 70% fraction are dissolved in 500 parts of water and the dye solution obtained is adjusted to pH 5.5-6.5. Evaporation or spray drying of this dye solution provides a dye mixture which provides red to reddish brown dyeings and prints on cotton under the dyeing conditions customary for reactive dyes. Example 9 326 parts of 4-(b-sulfatoethylsulfonyl)aniline are suspended in 800 parts of ice-water and 212 parts of 30% hydrochloric acid and diazotized by dropwise addition of 204 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid, this diazo suspension is added dropwise to an aqueous solution of 397 parts of the scarlet monoazo dye of the formula (15-1) (prepared as described in example 3), 147 parts of 4-aminonaphthalene-1-sulfonic acid are added as a second coupling component, and a pH of 5.5 - 6.5 is set with sodium carbonate at below 25°C. The 60 : 40 mixture of the two azo dyes (I-3) and (II-6) which has formed after the coupling reaction has ended is subsequently isolated by spray drying. The resulting dye mixture according to the present invention dyes cotton in reddish orange shades. Example 10 333 parts of 4-(b-sulfatoethylsulfonyl)aniline are suspended in 850 parts of ice-water and 214 parts of 30% hydrochloric acid and diazotized by dropwise addition of 205 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid solution, the diazo suspension obtained is pumped into an aqueous solution of 339 parts of the scarlet monoazo dye of the formula (15-3) which was obtained by diazotization of 180.5 parts of 2-amino-5-(b-sulfatoethyl- sulfonyl)benzenesulfonic acid with 87 parts of 40% sodium nitrite solution in an acidic medium and subsequent coupling onto 119 parts of 7-amino-4-hydroxy-naphthalene- 2-sulfonic acid at pH 1.5 to 2. This is followed by the addition of 140 parts each of the two further coupling components (18-2) and (18-3) and pH 5 — 6 is set and maintained with sodium carbonate below 25CC. The 50 : 25 : 25 mixture of the three dyes (1-1), (II-7) and (II-8) which has formed after the coupling reaction has ended can be isolated by evaporation under reduced pressure or by spray drying. The resulting dye mixture of the present invention dyes cotton in reddish orange shades. Example 11 281 parts of 4-(li-suIfatoethylsulfonyl)aniline are suspended in 700 parts of ice-water and 180 parts of 30% hydrochloric acid and diazotized by dropwise addition of 173 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid solution, the diazo suspension obtained is admixed with an aqueous solution of 83 parts of 4-hydroxy-7-(sulfomethylamino)naphthalene-2-sulfonic acid (obtained by reaction of 60 parts of 7-amino-4-hydroxynaphthalene-2-sulfonic acid with 37.5 parts of formaldehyde sodium bisulfite in an aqueous medium at pH 5.5 - 6 and 45°C) and adjusted to pH 1.5 with solid sodium bicarbonate. After the acidic coupling has ended, this reaction mixture has added to it an aqueous solution of 111 parts of 4-amino-phthalene-1-sulfonic acid as the second coupling component and is adjusted to and maintained at pH 5 - 6 with sodium carbonate below 25°C. After the coupling reaction has ended, the reaction mixture is admixed with 73 parts of the golden yellow azo dye of the formula (Ga-1) and the resulting 42 : 46 : 12 mixture of the three azo dyes (I-4), (II-6) and (Ga-1) is isolated by spray drying. The resulting dye mixture according to the present invention provides orange dyeings and prints on cotton for example under the dyeing conditions customary for reactive dyes. Example 12 281 parts of 4-(b-sulfatoethylsulfonyl)aniline are suspended in 700 parts of ice-water and 180 parts of 30% hydrochloric acid and diazotized by dropwise addition of 173 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid solution, the diazo suspension obtained is added to an aqueous solution of 397 parts of the scarlet monoazo dye of the formula (15-1), which was obtained by diazotization of 180.5 parts of 2-amino-5-(b-sulfatoethylsulfonyl)- benzenesulfonic acid with 87 parts of 40% sodium nitrite solution in an acidic medium and subsequent coupling onto 166.5 parts of 4-hydroxy-7-(sulfomethylamino)- naphthalene-2-sulfonic acid at pH 1.5. This is followed by the addition of 258 parts of the further coupling component (18-4) in the form of an aqueous solution and pH 5 - 6 is set and maintained with sodium carbonate below 25°C. After the coupling reaction has ended, the reaction mixture is admixed with 242 parts of the golden yellow azo dye of the formula (Ga-3) and the resulting 46 : 34 : 20 mixture of the three azo dyes (I-3), (II-9) and (Ga-3) is isolated by evaporation under reduced pressure or spray drying. Alternatively, the dye solution obtained can also be buffered at pH 5.5 - 6 by addition of a phosphate buffer and further diluted or concentrated to provide a liquid brand of defined strength. The resulting dye mixture according to the present invention dyes cotton in orange shades. Example 13 200 parts of 4-(b-sulfatoethylsulfonyl)aniline are suspended in 500 parts of ice-water and 129 parts of 30% hydrochloric acid and diazotized by dropwise addition of 125 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid, 67 parts of 4-hydroxy-7-(sulfomethylamino)naphthalene-2-sulfonic acid (prepared by reaction of 48 parts of 7-amino-4-hydroxynaphtha!ene-2-sulfonic acid with 32 parts of formaldehyde sodium bisulfite in an aqueous medium at pH 5.5 - 6 and 45°C) and also 23 parts of 2,4-diaminobenzenesulfonic acid are added and initially coupled in a first stage at pH 1 to 2 below 20°C to form a mixture of two monoazo dyes as per the formulae (15-4) and (Ga-2). The stated pH range is set and maintained during the coupling reaction by addition of solid sodium bicarbonate. After the first coupling has ended, 27 parts of the further coupling component (18-5) are added and pH 5.5 - 6.5 is subsequently set with sodium carbonate below 25°C. The 58 :13 : 29 mixture of the three azo dyes (I-4), (II-10) and (Gb-1) which has formed after the second coupling reaction has ended is isolated by spray drying. The resulting dye mixture according to the present invention dyes cotton in orange shades. Example 14 169 parts of 4-(b-sulfatoethylsulfonyl)aniline are suspended in 430 parts of ice-water and 109 parts of 30% hydrochloric acid and diazotized by dropwise addition of 105 parts of 40% sodium nitrite solution. After excess nitrite has been removed with sulfamic acid solution, the diazo suspension obtained is pumped into an aqueous solution of a mixture of 159 parts of the scarlet monoazo dye of the formula (15-1) and 188 parts of the yellow monoazo dye of the formula (Ga-4) which was formed by diazotization of 180.5 parts of 2-amino-5-(b-sulfatoethyl- sulfonyl)benzenesulfonic acid with 87 parts of 40% sodium nitrite solution in a sulfuric acid medium and subsequent coupling onto a mixture of 66.5 parts of 4-hydroxy-7- (sulfomethylamino)naphthalene-2-sulfonic acid and 56.5 parts of 2,4-diaminobenzenesulfonic acid at pH 1.5 to 2. This is followed by the addition of 22.5 parts of 4-aminonaphthalene-1-sulfonic acid as a further coupling component and pH 5 - 6 is set and maintained with sodium carbonate. The 40 : 10 : 50 mixture of the three dyes (I-3), (II-6) and (Gb-2) which has formed after the coupling reaction has ended can be isolated by evaporation under reduced pressure or by spray drying. Alternatively, the dye solution obtained can be buffered at pH 5.5 - 6 by addition of a phosphate buffer and further diluted or concentrated to provide a liquid brand of defined strength. The resulting dye mixture according to the present invention dyes cotton in orange to reddish orange shades. Examples 15 to 163 The table examples which follow describe further inventive mixtures of the dyes of the general formulae (I) and (II) and if appropriate (Ga) - (Gf), which are each listed in the form of the sodium salts. The mixing ratios are reported in percent by weight. The dye mixtures provide orange/scarlet to brownish red dyeings on cotton for example by the dyeing methods customary for reactive dyes. Use example 1 2 parts of a dye mixture obtained as per example 1-14 and 50 parts of sodium chloride are dissolved in 999 parts of water and 5 parts of sodium carbonate, 0.7 part of sodium hydroxide (in the form of a 32.5% aqueous solution) and, if appropriate, 1 part of a wetting agent are added. This dyebath is entered with 100 g of a woven cotton fabric. The temperature of the dyebath is initially maintained at 25°C for 10 minutes, then raised to the final temperature (40-80°C) over 30 minutes and maintained at the final temperature for a further 60-90 minutes. Thereafter, the dyed fabric is initially rinsed with tap water for 2 minutes and then with deionized water for 5 minutes. The dyed fabric is neutralized at 40°C in 1000 parts of an aqueous solution which contains 1 part of 50% acetic acid for 10 minutes. It is rinsed again with deionized water at 70°C and then soaked off at the boil with a laundry detergent for 15 minutes, rinsed once more and dried to provide a strong reddish orange to brownish red dyeing having very good fastness properties. Use example 2 4 parts of a dye mixture obtained as per example 1-14 and 50 parts of sodium chloride are dissolved in 998 parts of water and 5 parts of sodium carbonate, 2 parts of sodium hydroxide (in the form of a 32.5% aqueous solution) and if appropriate 1 part of wetting agent are added. This dyebath is entered with 100 g of a woven cotton fabric. The rest of the processing is carried out as reported in use example 1 to provide a scarlet dyeing having very good fastness properties. Use example 3 A textile fabric consisting of mercerized cotton is padded with a liquor containing 35 g/l of anhydrous sodium carbonate, 50 g/l of urea and 150 g/l of a low viscosity sodium alginate solution (6%) and then dried. The wet pickup is 70%. The thus pretreated textile is printed with an aqueous ink containing 8% of a dye mixture as per any of examples 1-14 20% of 1,2-propanediol 0.01 % of Mergal K9N and 71.99% of water using a drop-on-demand (bubble jet) inkjet print head. The print is fully dried. It is fixed by means of saturated steam at 102°C for 8 minutes. The print is then rinsed warm, subjected to a fastness wash with hot water at 95°C, rinsed warm and then dried. The result is an orange to red print having excellent service fastnesses.
