DYSTAR TEXTILFARBEN GMBH & CO. DEUTSCHLAND KG DYS 2000/D 515 Dr.KUN Description Metal complex Colouning Agents based on Bucherered naphthols The present invention relates to novel reactive dyes, processes for their preparation and their use for dyeing or printing textile fiber materials. Reactive dyes for dyeing or printing hydroxyl- and/or carboxamido-containing materials these days must combine good general fastness properties with good washoff of the unfixed portions. Given the dyes available at present, there is accordingly room for improvement. It is an object of the present invention to provide novel, improved reactive dyes for the dyeing and printing of hydroxyl- and/or carboxamido-containing materials, especially fiber materials, that combine good general fastness properties, especially a high lightfastness, with good washoff of the unfixed portions. This object is surprisingly achieved by the hereinbelow described dyes according to the invention. The present invention accordingly provides reactive copper, cobalt or chromium complex compounds of the general formula (1) where B is a direct bond or a bridge member; X is a fiber-reactive structural element; W1 is vinyl or a group of the formula - CH2-CH2-V, where V is an alkali- eliminable radical; R1, R2 are independently hydrogen, chlorine, alkyl of 1-4 carbon atoms, such as methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, tert-butyl, alkoxy of 1 -4 carbon atoms, such as methoxy, ethoxy, n-propyloxy, i-propyloxy, carboxyl or sulfamoyl, hydrogen, hydroxyl or sulfo, preferably hydrogen; R3 is hydrogen, hydroxyl, carboxyl or sulfo; R4 is hydrogen or sulfo; R5 is hydrogen, alkyl of 1 to 4 carbon atoms which can be substituted by halogen, hydroxyl, cyano, alkoxy of 1 to 4 carbon atoms, alkoxycarbonyl of 2 to 5 carbon atoms, carboxyl, sulfo or sulfato; h, k, I, m are independently 0 or 1; Me is copper, cobalt or chromium, preferably copper and cobalt and particularly preferably copper; M is hydrogen or an alkali metal, such as sodium, potassium or lithium, or the mole equivalent of an alkaline earth metal, such as calcium, and preferably is hydrogen or an alkali metal. Suitable fiber-reactive radicals X, i.e., those which react with the OH or NH groups of the fiber under dyeing conditions to form covalent bonds, are for example -SO2Ch = CH2 or -SO2CH2CH2V, where a V grouping, which can be eliminated through the action of alkali, represents in particular radicals of the formula -OSO3M, thiosulfato of the formula -SSO3M, acetyloxy of the formula -OCOCH3, phosphato of the formula -OPO(OM)2 and chloro, bromo, benzyloxy of the formula -OCOC6H5, phenylsulfonyloxy of the formula -SO2-C6H5 or pyridinium, which may be substituted, for example by alkyl of 1-4 carbon atoms, carboxyl, sulfo, cyano or carbamoyl, where M is as defined above, or are fiber- reactive radicals X, especially those which contain at least one reactive substituent attached to a 5- or 6-membered aromatic heterocyclic ring, for example to a monoazine, diazine or triazine ring, especially a pyridine, pyrimidine, pyridazine, pyrazine, thiazine, oxazine or asymmetrical or symmetrical triazine ring, or to such a ring system that comprises one or more fused-on aromatic carbocyclic rings, for example a quinoline, phthalazine, cinnoline, quinazoline, quinoxaline, acridine, phenazine or phenanthridine ring system.

For example, the dyes of the general formula (1-1) according to the invention are obtainable from amino compounds of the general formula (1-2) where R5" is hydrogen, methoxy or hydroxyl, X is SO2-W1 or SO2CH = CH2 or SO2CH2CH2V, where V is as defined above, and M, R1, and k are each as defined above, by diazotization and coupling onto a compound of the formula (1-3) where R2, R3, R4, W1, and m are each as defined above, at a temperature between 0°C and 90°C, preferably between 10°C and 40°C, and at a pH of less than 6, preferably between 0.5 and 4.0, and subsequent reaction with copper, cobalt or chromium donors similarly to known processes for synthesizing metal complexes. Amines of the general formula (1-2) used as diazo components in the process of the invention are for example 3- or 4-(p-sulfatoethylsulfonyl)antline, 2-amino- 4-(p-sulfatoethylsulfonyl)anisole, 2-amino- 5-(p-sulfatoethylsulfonyl)anisole, 2-methoxy-5-methyl-4-(p-sulfatoethylsulfonyl)aniline, 2,5-dimethoxy- 4-(p-sulfatoethylsulfonyl)aniline, 2,4-dimethoxy-5-(p-sulfatoethylsulfonyl)aniline, 4-amino-3-(p-sulfatoethylsulfonyl)anisole, 4-amino-3-(p-sulfatoethylsulfonyl) toluene, 4-(p-sulfatoethylsulfonyl)aniline-2-sulfonic acid, 2-chloro- or 2-bromo- 4-(p-sulfatoethylsulfonyl)aniline, 2-amino-4- or - 5-(P-sulfatoethylsulfonyl)phenol, 6-chloro-, 6-bromo- or 6-nitro-4-(p-sulfatoethylsulfonyl)phenol, 2-amino- 4-(P-sulfatoethylsulfonyl)phenol-6-sulfonic acid, 2-amino-4-methyl-5-(?-sulfato- ethylsulfonyl)phenol, 2-amino- 4-methoxy-5-(?-sulfatoethylsulfonyl)phenol and their corresponding vinylsulfonyl, p-thiosulfatoethylsulfonyl and ?-chloroethyl- sulfonyl compounds. The coupling components of the general formula (1-3) according to the invention are preferably prepared by Bucherer reaction of the corresponding naphthols or naphthylamines with 2-aminophenols of the general formula (1-5) where M, R2, W1, m and I are each as defined above. The conditions of the Bucherer reaction are known per se, for example from GB-A-230 457 and CS 155758; it is preferably carried out in water at 80°C and 130°C, particularly preferably between 100°C and 130°C. Starting compounds for the Bucherer reaction are for example 1 -hydroxy- 7-aminonaphthalene-3-sulfonic acid, 1,7-dihydroxynaphthalene-3-sulfonic acid, 2-aminonaphthalene-6-sulfonic acid, 2-aminonaphthalene-5-sulfonic acid, 2-hydroxynaphthalene-6-sulfonic acid, 2-hydroxynaphthalene-5-sulfonic acid, 1,6-dihydroxynaphthalene-3-sulfonic acid, 2-hydroxynaphthalene-7-sulfonic acid, 2-aminonaphthalene-7-sulfonic acid, 1 -hydroxy-6-aminonaphthalene-3-sulfonic acid, 2-aminonaphthalene-5,7-disulfonic acid, 2-hydroxynaphthalene-5,7-di- sulfonic acid and 2-aminophenol, 2-aminophenol-4-sulfonic acid, 2-aminophenol- 6-sulfonic acid, 2-amino-4-methylphenol, 3-amino-4-hydroxybenzoic acid, 3-amino-4-hydroxybenzoic acid, 3-amino-2-hydroxybenzoic acid, 4-amino- 3-hydroxybenzoic acid, 2-amino-4-(?-sulfatoethylsulfonyl)phenol, 2-amino- 4-(?-hydroxyethylsulfonyl)phenol-6-sulfonic acid. In a preferred embodiment of the preparative process, the Bucherer reaction was carried out using aminophenol of the general formula (1-5) where W2 is hydroxyethyl and I is 1. For instance, a compound of the general formula (1-4) where R3 and R4 are each as defined above and R6 is hydroxyl or amino, is adjusted to a pH of 5.7 in water and 39% sodium hydrogensulfite solution using 33% aqueous sodium hydroxide solution together with a compound of the general formula (1-5) where M, R2, W1, m and I are each as defined above. If appropriate, the addition of sodium chloride is followed by refluxing the reaction mixture at 100°C to 110°C for 20 hours. After cooling to room temperature, the product of the formula (1-3) where R2, R3, R4 and m are each as defined above, W1 is hydroxyethyl and I is 1, is isolated, washed with saturated sodium chloride solution and dried. The resultant compound of the general formula (1-3) where W1 is hydroxyethyl and I and m are each 1 is subsequently converted by customary methods, for example using anhydrous sulfuric acid as described in EP-A- 0568876, into the corresponding sulfuric ester, i.e., into a compound of the general formula (1-3) where W1 is ?-sulfatoethyl. The diazotization of the compounds of the general formula (1-2) and also the coupling reaction with the compound of the general formula (1-3) are known per se to one skilled in the art and can be carried out in the generally customary manner extensively described in the pertinent literature. The thus obtainable monoazo compounds of the general formula (1-6) where h is 0; B is a direct bond and X is S02W1 and -M, R1, R2, R3, R4, R5, R5", W1, I, m and k are each as defined above are new and likewise form part of the subject matter of the present invention. The compounds of the general formula (1-6) according to the invention are treated with a copper, cobalt or chromium donor in the presence or absence of an oxidizing agent or in the presence or absence of a demethylating agent. This reaction with copper, cobalt or chromium donors is effected similarly to known processes for synthesizing metal complexes. Monoazo compounds of the general formula (1-6) are preferably treated with the metal donors in an aqueous medium at a temperature between 0 and 130°C, if appropriate by refluxing or under superatmospheric pressure in a closed vessel. When metal complex formation is carried out as an oxidative coppering, i.e., when R5 is a hydrogen atom in the compounds of the formula (1-6), a customary oxidizing agent is added. The metal donors used in the metal complex formation process according to the invention are for example salts of copper, of cobalt and of chromium which are capable of donating the respective metal in the form of a cation to the complex formation capable hydroxyl groups in the compounds of the formula (1-1) which may have become formed in the oxidative or dealkylating metallization, for example copper sulfate, copper carbonate, cobalt sulfate, cobalt acetate and chromium sulfate; such compounds useful as metal complex formers also include hydroxycarboxylic acids or dicarboxylic acids which contain the metal bound in a complexed form, for example complex cobalt or chromium compounds of aliphatic hydrocarboxylic acids or of aliphatic dicarboxylic acids, especially of alkanes of 2 to 6 carbon atoms, or chromium complex compounds of aromatic o-hydroxycarboxylic acids, for example the chromium or cobalt complex compounds of salicylic acid, of citric acid, of lactic acid, of glycolic acid or of tartaric acid. The monoazo compounds of the general formula (1-1) according to the invention can be separated and isolated from the aqueous synthesis solutions according to generally known methods for water-soluble compounds, for example by precipitating from the reaction medium by means of an electrolyte, for example sodium chloride or potassium chloride, or by evaporating the reaction solution itself, for example by spray drying. When the latter form of isolation is chosen, it is frequently advisable to precede the evaporating by removing any sulfate present in the solutions by precipitation as calcium sulfate and removal by filtration or pressure permeation. The dyes of the general formula (1) according to the invention are further obtainable for example by reacting equivalent amounts of amino compounds of the general formula (3a) and (3b) where Me, R1 to R10 I, m, k, x, y and z are each as defined above, with a compound of the general formula (4) where R11, R12, B1 and Hal are each as defined above, or first reacting a compound of the general formula (3a) with a compound of the general formula (5) and a compound of the general formula (3b) with a compound of the general formula (5). The compounds thus obtained are subsequently reacted with each other with the stoichiometric amount of compound (6) where R11, R12, B1 are each as defined above. Particularly preferred compounds of the general formula (5) are 2,4,6-trifluoro- 1,3,5-triazine and 2,4,6-trichloro-1,3,5-triazine. Diamino starting compounds of the general formula (6) include for example 1,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminobutane, 1,6-diaminohexane, 1,4-diaminocyclohexane, 1,3-diaminocyclohexane, 4-methylaminoaniline, 1,3-diaminobenzene-4-sulfonic acid, 1,4-diaminobenzene-3-sulfonic acid, 1,3-diaminobenzene-4,6-disulfonic acid, p-aminobenzenemethylamine, p-phenylenediamine, m-phenylenediamine, aminoethylpiperazine, o-phenylenediamine, m-toluenediamine, 2,4-diaminoanisole, piperazine, 1,1-bis- (4"-aminophenyl)cyclohexane, benzidine, 4,4"-diamino-3,3"-dimethoxybiphenyl- 6,6"-disulfonic acid, 3,3"-dimethyl-4,4"-diaminobiphenyl-6,6"-disulfonic acid, 1,5-diaminopentane, N-(2-aminoethyl)piperazine, bis(2-aminoethyl) ether, 1,5-diaminonaphthalene, 1,8-diaminonaphthalene, 2,6-diaminonaphthalene- 4,8-disulfonic acid, 1,6-diaminonaphthalene-4,8-disulfonic acid, 4-(4"-amino- phenylcarbonylamino)aniline and 3-(4"-aminophenylcarbonylamino)aniline, of which preferably 1,4-diaminobenzene-3-sulfonic acid and 1,3-diaminobenzene- 4,6-disulfonic acid and particularly preferably 1,2-diaminoethane, 1,3-diamino- propane, 1,6-diaminohexane, piperazine, 1,3-phenylenediamine and 1,4-phenylenediamine, 4-aminobenzylmethylamine, 3-aminobenzylmethylamine. Further useful dyes of the general formula (1) are obtained by reacting compounds of the general formula (3a) with compounds of the general formula X-Hal, where X and Hal are each as defined above. In a particular embodiment, compounds of the general formula (3a) are reacted with compounds of the general formula in a conventional manner. Alternatively, compounds of the general formula (3a) are first reacted with preferably cyanuric chloride or cyanuric fluoride and then with amines of the general formula AH, where AH is as defined above. The process steps described are comprised in the prior art. The invention further provides a process for preparing compounds of the general formula (3) where R1 to R5, Me and B, k, I, m, W1, M are each as defined above. Compounds of the general formula (3) are new and likewise form part of the subject matter of the invention. They are obtainable starting from amino compounds of the general formula (8a) or (8b) where L is a hydrolyzable protecting group, for example formyl, C1-C4-alkyl- carbonyl or C1-C4-alkoxycarbonyl, especially acetyl, and M, B, R1 and R5 and also k are each as defined above, by diazotization and coupling onto a compound of the formula (1-3) where R2, R3, R4, W1 I and m are each as defined above, at a temperature between 0°C and 3D°C, preferably between 10°C and 40°C, and at a pH less than 6, preferably between 0.5 and 4.0, and subsequent reaction with copper, cobalt or chromium donors similarly to familiar processes for synthesizing metal complexes, and subsequent reduction of the nitro group in a conventional manner or hydrolysis, preferably alkaline hydrolysis, similarly to known procedures, of the protected amino group. Amines of the general formula (8a) and (8b) which are used as diazo components in the process according to the invention include for example: 6-acetylamino-2-aminophenol-4-sulfonic acid, 2-amino-6-nitrophenol-4-sulfonic acid, 4-nitro-2-aminophenol-6-sulfonic acid, 2-amino-6-chlorophenol- 4-N-hydroxyethylsulfonamide, 4-nitro-2-aminophenol, 5-nitro-2-aminophenol, 4-chloro-6-nitro-2-aminophenol, 4-chloro-6-nitro-2-aminophenol, 4-chloro-5-nitro- 2-aminophenol, 6-chloro-4-nitro-2-aminophenol, 2-aminophenol-4-sulfonamide, 4-acetylamino-6-aminophenol-2-sulfonic acid. The reactive dyes of the general formula (1) according to the invention possess useful application properties. They are used for the dyeing and printing of hydroxyl- and/or carboxamide-containing materials, for example in the form of sheetlike structures, such as paper and leather, or of films, of polyamide for example, or in bulk, as for example polyamide and polyurethane, but especially in the form of fibers of the materials mentioned. Preferably they are used for dyeing and printing cellulosic fiber materials of any kind. They are also useful for dyeing and printing hydroxyl-containing fibers present in blend fabrics, for example blends of cotton with polyester fibers or polyamide fibers. It is also possible to use them to print textiles or paper by the inkjet process. The present invention accordingly also provides for the use of the reactive dyes of the general formula (1) according to the invention for dyeing or printing the materials mentioned and processes for dyeing or printing such materials in a conventional manner by using one or more reactive dyes of the general formula (1) according to the invention as a colorant. For this, the as-synthesized solutions of the reactive dyes of the general formula (1) according to the invention can be used directly as a liquid preparation for dyeing, if appropriate after addition of a buffer substance and similarly if appropriate after concentrating. Hydroxyl-containing materials are those of natural or synthetic origin, for example cellulose fiber materials or regenerated products thereof 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. Carboxamido-containing materials are for example synthetic and natural polyamides and polyurethane, 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 fiber materials can also be processed and dyed in blends with each other or contain fiber materials of a different chemical nature, such as polyester fibers. Examples thereof are blend fabrics of cellulose fibers and polyester fibers and also of cellulose fibers and polyamide fibers. The dyes 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, fiber-reactive dyes, in accordance with the use of the invention, for example by applying the compounds of the general formula (1) in dissolved form to the substrate or incorporating them thereinto and fixing them thereon or therein by heating or by the action of an alkaline agent or by both measures. Such dyeing and fixing processes are extensively described in the literature, for example in EP-A-0 181 585. Thus the compounds (1) are useful not only for the exhaust dyeing process but also for dyeing by the pad dyeing process, whereby the material is impregnated with aqueous solutions of the dyes according to the invention, which may contain electrolyte salt, and fixed on the material in the manner mentioned above. The compounds of the general formula (1) according to the invention are particularly useful for cold pad-batch processes, whereby a dye is applied to the fiber material on a pad mangle together with alkali and is fixed by storing at room temperature for several hours. After fixing, the dyeings and prints obtained are thoroughly washed with cold and hot water, if appropriate in the presence of an agent which has a dispersing action and promotes the diffusion of unfixed portions. The compounds of the general formula (1) are notable for high reactivity, good flexibility and good build-up capacity. They can therefore be used for exhaust dyeing at low dyeing temperatures and require only short steaming times in pad- steam processes. The fixation yields are high, and the unfixed portions are readily washed off with the difference between the degree of exhaustion and the degree of fixation being remarkably small, i.e., the loss through hydrolysis being very small. The compounds of the general formula (1) are also particularly useful in textile printing processes, especially on cellulose fiber materials, such as cotton, but also for printing carboxamide-containing fiber material, for example wool and silk, or blend fabrics containing wool or silk. They are similarly very useful in discharge printing and resist printing processes. The dyeings and prints prepared with the compounds of the general formula (1) according to the invention, on cellulose fiber materials in particular, have a high color strength and a high fiber-dye bond stability not only in the acidic but also in the alkaline range, also good lightfastness, including very good wet lightfastness, and also generally good wetfastnesses, such as good fastness to washing, water, seawater, crossdyeing and perspiration, and also very good perspiration lightfastnesses, further good fastness to pleating and dry heat setting and rubbing. The examples which follow illustrate the invention. The compounds described in the examples by means of a formula are indicated in the form of the free acids; generally they are prepared and isolated in the form of their alkali metal salts, such as lithium, sodium or potassium salts, and used for dyeing in the form of their salts. Similarly, the starting compounds and components mentioned in the examples hereinbelow, especially the table examples, in the form of the free acid may be used in the synthesis as such or in the form of their salts, preferably alkali metal salts. The absorption maxima (?max) in the visible region reported for the compounds of the invention were determined on their alkali metal salts in aqueous solution. The table examples report the ?max values in brackets next to the hue; the wavelength is given in nm. Preparation of the dyes of the general formula (1-1) according to the invention 1.
