DYE MIXTURES OF FIBER-REACTIVE AZO DYES AND PREPARATION AND USE THEREOF This invention relates to the technical field of fiber-reactive azo dyes. Mixed fiber-reactive azo dyes and heir use for dyeing hydroxyl- and carboxamido- containing material in black shades are known for example from the documents US 5,445,654, US 5,611,821, KR 94-2560, Sho 58-160362 and EP-A-0 870 807. However, they have certain applica ion defects, such as for example an overly large dependence of the color yield on varying dyeing parameters in the dyeing process or an insufficient or unlevel color build-up on cotton (good color build-up results from the ability of a dye to provide a proportionally stronger dyeing when used in higher concentrations in the dyebath), or an excessive salt dependence of the dyeings. Consequences of these defects can be poor reproducibilities for the dyeings that are obtainable. The documents WO 98/42784, WO 98/42785, WO 93/18224 and US 5,330,539 disclose dyes and dye mixtures which can be dyed in the presence of small amounts of sals, but which provide only very weak dyeings in the absence of salt. Since it is commercially as well as en /ironmentally necessary to reduce the salt content of dyeing effluent, there is a need for reactive dyes which provide dyeings of high color strength in the presence of small amounts of salt or even in the absence of electrolyte salts. The present invention, then, provides dye mixtures which provide.dyeings of high coTor strength in the presence of only very low levels or even in the absence of electrolyte salts. The invention accordingly provides dye mixtures comprising one or more, such as two or three, preferably 1 or 2, dyes of he hereinbelow indicated and defined general formula (I) one or more, such as two or three, preferably 1 or 2, dyes of the hereinbelow indicated and defined general formula (II) and, optionally, as further component; for blending or shading, one or more, such as two or three, preferably 1 or 2, dyes having, for example, the hereinbelow indicated and defined general formulae (Illa) - (llIf) where R1 is hydrogen, (C1-C@@@4)-aIkyl, aryl or a substituted aryl radical; R2 and R3 are independently hydrogen, (C1-C@@@4-alkyl, (C1-C@@@4)-alkoxy, hydroxyl, sulfo, carboxyl, arrido or halogen; and A is a phenylene group of the general formula (2) where R4 and R5 are independently hydrogen, (CrC4)-alkyl, (C1-C@@@4)- alkoxy, hydro;:yl, sulfo, carboxyl, amido or halogen; or a naphthylene group of the general formula (3) where R6 and R7 are independently hydrogen, (C1-C@@@4)-alkyl, (C1-C@@@4)- alkoxy, hydroxyl, sulfo, carboxyl, amido or halogen; or a polymethylene gr )up of the general formula (4) -(CR8R9)k- (4) where k is an in .eger greater than 1 and R8 and R9 a e independently hydrogen, (C1-C@@@4)-alkyl, (C1-C@@@4)- alkoxy, hydnxyl, cyano, amido, halogen or aryl; and X1 is hydrogen or a group of the formula -SO2-Z; or are each a phenyl group of the general formula (5) where R10 and R11 are indepenc ently hydrogen, (C1-C@@@4)-alkyl, (C1-C@@@4)-alkoxy, hydroxy), sulfo, carboxyl, amido or halogen; and X2 has one of the meanings of X1; or are each a naphthyl group of the general formula (6) where R12 and R13 are independently hydrogen, (C1-C@@@4)-alkyl, (C1-C@@@4)-alkoxy, hydroxyl, sulfo, carboxyl, amido or halogen; and X3 has one of the meanings of X1; Z is -CH=CH2, -CH2CH2Z' or hydroxyl, where Z1 is hydroxyl or an alkali-eliminable group; and M is hydrogen, an alkali rr etal or one equivalent of an alkaline earth metal; D3 has one of the meanings of D1 or D2 or is a group of the general formula (7) where R21 and R22 independently have one of the meanings of R2and R3; R23 is hydrogen, (C1- C4)-alkyl, unsubstituted or (C1-C@@@4)-alkyl-, (C1-C@@@4)- alkoxy-, sulfo-, hale gen- or carboxyl-substituted phenyl; and Z21 is a fiber-reactive croup of the general formula (8) or (9) or (10) where V is fluorine or chlorine; U1 and U2 are incependently fluorine, chlorine or hydrogen; and Q1 and Q2 are independently chlorine, fluorine, cyanamido, hydroxyl, (C1-C6)-alkoxy, phenoxy, sulfophenoxy, mercapto, (C1-C6)- alkylmercapto, pyridine carboxypyridino, carbamoylpyridino or a grouf of the general formula (11) or (12) or phenyl which is unsubstituted or substituted by (C1-C4 )-alkyl, (C1-C4)-alkoxy, sulfo, halogen, carboyl, acetamido or ureido; R ' and R4' independently have one of the meanings of R2', or con bine to form a cyclic ring system of the formula -(CH2)-, where j is 4 or 5, or alternatively -(CH2)2-E- (CH2);-, where E is oxygen, sulfur, sulfo, -NR5'-, where R5' is aqua! to (C1-C6)-alkyl, or they are a group of the general formula (13) where R24, R25 and R26 are each (C1-C4)-alkyl or (C1-C4)- hyd oxyalkyl; and B" is the equivalent of an anion, such as hydrogensulfate, sulfate, fluoride, chloride, bromide, dihydrogenphosphate, hydrogenphosphate, phosphate, hydroxide or acetate; W is phenylene which is unsubstituted or substituted by 1 or'.'. substituents, such as (C1-C4)-alkyl, (C1-C4)-alkoxy, caiboxyl, sulfo, chlorine, bromine, or is (C1-C4)- alkylene-arylene or (C2-C6)-alkylene, which can be int irrupted by oxygen, sulfur, sulfo, amino, carbonyl, ca boxamido, or is phenylene-CONH-phenylene, which is jnsubstituted or substituted by (C1-C4)-alkyl, (C1-C4)- alkoxy, lydroxyl, sulfo, carboxyl, amido, ureido or haloger, or is naphthylene, which is unsubstituted or substiti ted by one or two sulfo groups; and Z is as d afined above; R is hydrogen, (C1-C4)-alkyl or phenyl which is unsubstituted or substituted by (C1-C4)-alkyl, (C1-C4)-alko) y, sulfo, halogen, carboxyl, acetamido or ureido; or is a group of the formula (14) CH2-SO3M (14), where M is as defi led above; and n is 1 or 2, D4, D5, D6, D7 and D8 have one of the meanings of D1, D2 or D3, and, if R31 is nol a group of the general formula (8) or (9), D4, and also D5 or 36 and D8, contain at least one fiber-reactive group of the formula -SO2Z or Z21; R31 is hydrogen, acetyl, carbamoyl, sulfomethyl or a group of the general formula (8) or (9), R32 is hydrogen or sulfomethyl, R33 is methyl, carboxyl or carboxyalkyl, with C1-C4-alkyl, R34 is hydrogen or methyl, R35 is hydrogtin, cyano, carbamoyl, carboxyl or sulfomethyl, R36 is methyl ethyl or (i-sulfoethyl, R37 is methyl carboxyl or carboxyalkyl, with C1-C4-alkyl, R38 is acetaniido, ureido or methyl, R39 is hydrogen, methyl or methoxy, m is O or 1, p is 1, 2 or 3, and Z has one of the meanings of Z21.

Subsequently an amine of the general formula (18) D - NH2 (18), where D2 is as defined above is diszotized in a conventional manner and the resulting diazonium compound is then coupled in a second stage with the mixture of the monoazo dyes of the general formulae (15) and (II) obtained in the first stage, coupling taking place at a pH of between 3 and 7.5, to give a mixture of the dyes of the general formulae (I) and (II). Alternatively, where the diazo cormonents with the groups D1 and D3 in the general formulae (I) and (II) possess the same meaning (D1 = D3), the dye mixture of the invention can be prepared by conventionally diazotizing an amine of the general formula (18), where D1 is as defined in claim 1, and then reacting the resulting diazonium compound of an aqueo iS solution or suspension of a mixture of defined proportion of a red monoazo dye of the general formula (15) and an optionally substituted 6-amino-4-hydroxynaphthalene-2-sulfonic acid, first with a pH below 3 to give a mixture of two red monoazo dyes of the general formulae (15) and (II), and, when acidic coupling is at an end, by raising the pH to 4 - 7.5, carrying out the second coupling of the monoazo dye of the general formula (15), giving a mixture of the two dyes of the general formula ae (I) and (II). The red monoazo dyes of the general formula (15) can be prepared by conventionally diazotizing an amine of the general formula (17), where D2 is as defined in claim 1, and then coupling the resulting diazonium compound in an aqueous medium at a pH below 2 with 4-amino-5-hydroxyna phthalene-2,7-disulfonic acid and/or 4-amino-5- hydroxynaphthalene-1,7-disulfonic acid in a first stage. The dye mixture of the invention is solated in a conventional manner, where appropriate following the addition o one or more, such as two or three, yellow components of the general formulae (Illa) to (lllf), in solid form or as an aqueous solution, by salting out for example with sodium chloride or potassium chloride or by spray drying. Additionally, the as-synthesized solutions of the dye mixtures of the general formula (I) and (II) can be used directly as a liquid preparation for dyeing, where appropriate following addition of one or more, such as two or three, yellow components of the general formulae (Illa) to (lllf) in solid form or as aqueous solutions and also, where appropriate, addition of a buffer substance and, where appropriate, after concentration or dilution. Dye mixtures which as well as β-chloroethylsulfonyl or p-thiosulfatoethylsulfonyl or p- sulfatoethylsulfonyl groups also coniain vinylsulfonyl groups as reactive radicals can be synthesized not only starting from appropriately substituted vinylsulfonylanilines or naphthylamines but also by reaction of a dye mixture where Z is p-chloroethyl, p- thiosulfatoethyl or β-sulfatoethyl with an amount of alkali required for the desired fraction and converting the β-substituted ethylsulfonyl groups mentioned into vinylsulfonyl groups. This conversior is effected in a manner familiar to one skilled in the art. The d'ye mixtures according to the invention have useful application properties. They are used for dyeing or printing hydrocyI-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, as for example polyamide and polyurethane, but especially for dyeing and printing these materials in fiber form. The present invention thus also provides for the use of the dye mixtures according to the invention for dyeing or printing those 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 preferatly 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 01 fibers as described for example in WO 96/37641 and WO 96/37642 and also in EP 0 538 785 and EP 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 nylon-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 build-up on cellulose fibers, the dyes being fixable in a conventional manner by batching at room temperature o elevated temperature, for example at up to about 60°C, or in a continuous manne; for example by means of a pad-dry-pad steam process, by steaming or using cry heat. Similarly, the customary printinc 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 hot electrolyte- containing alkaline bath or by overpadding with an alkaline electrolyte-containing padding liquor and subsequent batching of the alkali-overpadded material or subsequent steaming or subsequent dry heat treatment of the alkali-overpadded material, produce strong prints with well-defined contours and a clear white ground. The outcome of the prints is litt e affected, 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 likew se 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 a aids, the preferred alkali metal compounds being the sodium and potassium compounds. Such acid-binding agents are for example sodium hydroxide, potassium nydroxide, sodium carbonate, sodium bicarbonate, potassium carbonate, sodium formate, sodium dihydrogenphosphate, disodium hydrogenphosphate, sodium t ichloroacetate, trisodium phosphate or waterglass or mixtures thereof, for example mixtures of aqueous sodium hydroxide solution and waterglass,. 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. For instance, no electrolyte salt is equired for a shallow depth of shade, not more than 5 g/l of electrolyte salt is requred for a medium depth of shade and not more than 10 g/l of electrolyte salt is recured 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 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 dyeings 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, watar, 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 29a); J. Soc. Dyars and Colourists 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 aminobenzem sulfonic 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 o 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 at out, especially for very deep dyeings, the full reactive bond between the dyes o 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 natu al polyamides or of synthetic polyamides and polyurethanes. In general, the material to be dyed is introduced into the bath at a temperature of about 40°C, agitated therein for some time, the dyebath is then adjusted to the desired weakly ac dic, 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 a' 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 navy to jet black shades having 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. 1 he 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 forrr of their salts, preferably sodium or potassium salts, and used for dyeing in the form c f their salts. The starting compounds described in the examples hereinbelow 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.

This dyebath is entered with 100 g of a cotton fabric. The temperature of the dyebath is first maintained at 25°C for 10 minutes, then raised over 30 minutes to the final temperature (40-60°C) and mainta ned at that level for a further 60-90 minutes. Thereafter, the dyed material is rinsed initially with tap water for 2 minutes and then with ion-free water for 5 minutes. The dyed material is neutralized at 40°C in 1000 parts of an aqueous solution containing 1 part of 50% acetic acid for 10 minutes. It is subsequently rinsed with ion-free water at 70°C and thereafter soaped off at the boil with a detergent for 15 minutes, rinsed once more and dried.
