     An important process comprises condensing a dye of the formula ##STR42## first with an s-triazine of the formula ##STR43## and then condensing the compound obtained of the formula ##STR44## with a diamine of the formula ##STR45## then again with an s-triazine of the formula (32) and finally with an amine of the formula 
     
         H--A                                                       (34) 
    
     In a modified process, reactive dyes of the formula (1) can be prepared by reacting a component of this dye which contains a radical of the formula ##STR46## in which R and hal are as defined above, with a second component required for preparing the dye, which can, if desired, contain a radical of the formula (36), and condensing the resulting dye of the formula ##STR47## with a diamine of the formula (33), a further s-triazine of the formula (32) and an amine of the formula (34). 
     Effectively, it depends on the structure of the starting materials which of the possible process variants produce the best results or under which specific conditions, for example at which condensation temperature, the reaction should best be carried out. 
     Since under certain preconditions hydrolysis of the halotriazine radical occurs, it is necessary to hydrolyze an acetylamino-containing intermediate, to remove the acetyl groups, before condensation with a halotriazine. Which reaction is advantageously carried out first, for example the preparation of a secondary condensation product of a compound of the formula (33), the triazine of the formula (32) and the organic dye of the formula (31) or a precursor, that of the triazine with the compound of the formula (33) or that with the organic dye or a precursor of the dye, will vary from case to case and will depend in particular on the solubility of the amino compounds involved and on the basicity of the amino groups to be acylated. 
     A modified embodiment of the process comprises first preparing a dye which contains a preliminary stage of the reactive radical and subsequently converting this preliminary stage into the final stage, for example by esterification or an addition reaction. For example, a dye in which Z is an HO--CH 2  CH 2  -- radical can be prepared and, before or after the acylation, the intermediate can be reacted with sulfuric acid, so that the hydroxyl group is converted into a sulfato group; or an analogous dye is used in which Z is an H 2  C═CH-- group and thiosulfuric acid is added onto this intermediate to form an HO 3  SS--CH 2  CH 2  -- radical. The sulfation of the hydroxyl group in a dye of the formula (1) or in a suitable precursor is effected for example by reaction with concentrated sulfuric acid at 0° C. to moderately elevated temperature. The sulfation can also be effected by reaction of the hydroxy compound with two equivalents of chlorosulfonic acid per hydroxyl group in a polar organic solvent, for example N-methylpyrrolidone, at 10° to 80° C. Preferably, the sulfation is effected by introducing the compound in question into sulfuric acid monohydrate at temperatures between 5° and 15° C. The introduction of another radical for Z in a compound of the formula (1) or an intermediate in place of a halogen atom or the sulfato group, for example a thiosulfato or phosphato group, is effected in a manner known per se. The preparation via an intermediate of the reactive radical proceeds in many cases uniformly and to completion. 
     In addition, the synthesis can be followed by elimination reactions. For example, reactive dyes of the formula (1) which contain sulfatoethylsulfonyl radicals can be treated with hydrogen halide eliminators, such as sodium hydroxide, and the sulfatoethylsulfonyl radicals become converted into vinylsulfonyl radicals. 
     It may also be possible to use a process variant where the starting materials are dye precursors. This variant is suitable for preparing reactive dyes of the formula (1) in which D is the radical of a dye composed of two or more than two components, for example a monoazo, disazo, trisazo, metal complex azo, formazan or azomethine dye. 
     Generally, the reactive dyes of the formula (1) of all dye classes can be prepared in a manner known per se or analogously to known methods by starting from precursors of or intermediates for dyes which contain fibre-reactive radicals of the formula (1) or by introducing these fibre-reactive radicals into intermediates of dye character which are suitable for this purpose. 
     Preference is given to reactive dyes of the formula (1) in which D is the radical of a monoazo or disazo dye or of a metal complex azo dye. In this case, the reactive radicals of the formula ##STR48## are bonded to the diazo and/or coupling components. If two radicals of the formula (1a) are present in a reactive dye of the formula (1), preferably each radical of the formula (1a) is bonded to one component, i.e. to a diazo component or coupling component. The reactive dyes thus have for example the formulae ##STR49## in which R&#39; and R&#34; are independently of each other defined in the same way as B 1  in the formula (1), D 1  is the radical of a diazo component, K is the radical of a coupling component, and  ○R  is a reactive radical of the formula (1a). 
     If the starting materials are dye precursors, the reactive dyes of the formula (1) are obtained by condensing a component of the dye of the formula (31) containing an --N(R)H group and a triazine of the formula (32), condensing beforehand or afterwards with a compound of the formula (33), and reacting with the other component of the dye of the formula (31). In the preparation of the preferred azo dyes, the diazo components and the coupling components together need to contain at least one amino group --N(R)H and can contain further amino groups. In this case th diazo components used are in particular 1,3-phenylenediamine-4-sulfonic acid, 1,4-phenylenediamine-2-sulfonic acid, 1,4-phenylenediamine-2,5-disulfonic acid and 1,3-phenylenediamine-4,6-disulfonic acid. 
     If desired, it is possible to use corresponding acetylamino or nitro compounds in which the acetylamino or nitro group is converted into an H 2  N group, by hydrolysis and reduction respectively, before the condensation with the triazine of the formula (32). 
     If groups capable of metal complex formation are present in the reactive dyes prepared, such as hydroxyl, carboxyl, amino or sulfo, the reactive dyes can subsequently also be metallized. For example, metal complex azo dyes are obtained by treating azo compounds which have been obtained according to the invention and which contain complexing groups, for example hydroxyl or carboxyl groups, in the ortho-ortho&#39;-position relative to the azo bridge, with heavy metal donor agents before or if desired even after the condensation with a triazine of the formula (32). Of particular interest are copper complexes of reactive dyes of the formula (1). In addition to the method of metallization mentioned above, other suitable methods are dealkylating metallizatiion and, for the preparation of copper complexes, oxidative copperring. 
     The most important process variants are illustrated in the working examples. 
     In what follows, possible starting materials which can be used for preparing the reactive dyes of the formula (1) will be mentioned individually.

     Metal complexes of dyes of the formulae: ##STR51## 
     Preferred metal atoms are Cu (1:1 complex) or Cr and Co (1:2 complex). Cr- and Co-complexes can contain the azo compound of the abovementioned-formula once or twice, i.e. they can be constructed symmetrically or, using any other desired ligands, asymmetrically. ##STR52##

Preferably, radicals R 17  to R 23  and R 30  to R 33  are hydrogen, methyl or ethyl, and the radicals R 15 , R 16 , R 24  to R 29  are hydrogen, methyl, ethyl, methoxy, ethoxy, acetylamino, ureido or chlorine. The aromatic rings in the above dyes can be further substituted, the benzene rings in particular by methyl, ethyl, methoxy, ethoxy, methylsulfonyl, ethylsulfonyl, carboxyl, acetylamino or chlorine, and the naphthalene rings in particular by methoxy, carboxyl, acetylamino, nitro or chlorine; the same is true of the anthraquinones, dioxazines and the like.

     Amines of the formula (34) 
     Amines of the general formula (34) are known or can be prepared by known processes. Those amines which form the radical of the formula (5) can be prepared by condensing corresponding nitrophenyl-, nitrophenoxy, or nitrophenylamino-alkanoyl chlorides or analogous naphthalene compounds with amines of the formula 
     
         H--R&#39;                                                      (40) 
    
     which correspond to the radicals of the formulae (3) to (3d), and reducing the nitro group to an amino group. 
     The reaction is preferably carried out in a high-boiling organic solvent, for example nitrobenzene. The reduction of the nitro group to an amino group is effected in a manner know per se by catalytic hydrogenation with Pd/carbon in ethanol, ethyl acetate or tetrahydrofuran at room temperature to about 40° C. The reduction can also be carried out with Fe/hydrochloric acid or Fe/acetic acid in aqueous solution. 
     According to another method, described in DE Offenlegungsschrift 2,040,620, the acid chloride can be reached with an unsaturated aliphatic amine, and 2-mercaptoethanol can be added onto the double bond of the acid amide with the aid of catalytic amounts of a free radical former or sulfur at temperature between 50° C. and 180° C. The hydroxyethyl thioether compounds obtained as a result can also be prepared by condensing the acid chloride with a haloalkylamine and heating the condensation product in alcohol with 2-mercaptoethanol and sodium alkoxide. The thioether compounds are then oxidized to the corresponding sulfones. 
     The oxidation of the thioether compounds to sulfones can be carried out by various methods, for example with hydrogen peroxide with or without tungsten or vanadium compounds as catalysts, and also with peracetic acid, potassium permanganate or chromic acid, or with chlorine/hydrochloric acid, in each case in an aqueous, aqueous-organic or organic medium. 
     The carboxamides thus obtainable, where the grouping --SO 2  --Z is a β-hydroxyethylsulfonyl group, can be converted, by treatment with sulfating agents, phosphorylating agents, halogenating agents, alkylsulfonic or arylsulfonic acid halides, alkylcarboxylic or arylcarboxylic acid halides or alkylcarboxylic or arylcarboxylic anhydrides, into the corresponding dye precursors where the grouping --SO 2  --Z is for example an SO 2  --CH 2  --CH 2  --O--SO 3  H, --SO 2  --CH 2  --CH 2  --O--PO 3  H 2 , --SO 2  --CH 2  --CH 2  -- halogen, --SO 2  --CH 2  --CH 2  --O--CO--CH 3  or --SO 2  --CH 2  --CH 2  --O--CO--C 6  H 5  grouping. The products thus obtained can in turn be converted by treatment with alkaline agents, for example alkali metal hydroxide or alkali metal carbonate, such as sodium hydroxide or sodium carbonate, into corresponding compounds where the grouping --SO 2  --Z is a --SO 2  --CH═CH 2  grouping. The products thus obtained can again be converted by reaction (addition) with salts of thiosulfuric acid, such as sodium thiosulfate, into compounds in which the grouping --SO 2  --Z is an --SO 2  --CH 2  --CH 2  --S--SO 3  H grouping. 
     Suitable sulfating agents are here for example concentrated sulfuric acid and also chlorosulfonic acid and amidosulfuric acid or other sulfur trioxide donor compounds. Suitable phosphorylating agents are here for example concentrated phosphoric acid, pyrophosphoric acid, metaphosphoric acid, polyphosphoric acid, alkyl polyphosphates, phosphorus oxychloride or mixtures of phosphoric acid and phosphorus (V) oxide. Suitable halogenating agents are for example thionyl chloride and thionyl bromide. 
     Preference is given to compounds of the formula ##STR54## in which R&#39; is a radical of the formula ##STR55## B 3 , B, Z, alk, T, V, R 1 , alk&#39;, m, p and q are as defined under the formula (5), and R 2  is hydrogen, C 1  -C 4  alkyl, C 1  -C 4  alkoxy, halogen, hydroxyl, carboxyl or sulfo. In the compounds of the formula (41), preferably B 2  is methyl, ethyl, isopropyl or in particular hydrogen, R 2  is methyl, methoxy, chlorine, hydroxyl, carboxyl, sulfo or in particular hydrogen, B is methylene, methyleneoxy, propylene, propylenoxy or butyleneoxy, R&#39;  is one of the abovementioned radicals of the formulae (3a) to (3d). 
     The preferred process for preparing the compounds of the formula (41) comprises condensing a compound of the formula ##STR56## with an amine of the formula ##STR57## and reducing the nitro group to an amino group. 
     In a modified version of the process described above, compounds of the formula (41) can also be prepared by condensing a compound of the formula (42) with an amine of the formula ##STR58## oxidizing the condensation product with elemental chlorine to the corresponding β-chloroethylsulfonyl compound, and reducing the nitro group to an amino group. 
     In another possible process variant, first a compound of the formula (42) is condensed with one of the amines of formulae (44a) to (44d). The product obtained is oxidized with a peroxide to a sulfone, the nitro group is then reduced to an amino group, the amino compound obtained is condensed with an s-triazine of the formula (32) and finally the hydroxyl group in the radical of one of the amines of the formulae (44a) to (44d) is sulfated. 
     The condensation of the compound of the formula (42) with the amines of the formulae (44a) to (44d) is carried out for example in chloroform at room temperature and in the presence of alkaline, acid-binding agents, for example alkali metal hydroxides, alkali metal carbonates or alkali metal bicarbonates. The condensation product is then oxidized with a chlorine/hydrochloric acid mixture in a manner known per se. The reduction of the nitro group to an amino group is carried out as described above.

     The condensation of the s-triazine of the formula (32), in particular of a 2,4,6-trihalo-s-triazine, with the organic dyes of the formula (31) or with the diazotizable and/or couplable components containing an --N(R)H group is preferably effected in aqueous solution or suspension, at low temperatures, for example between 0° and 5° C., and at a weakly acidic, neutral or weakly alkaline pH. Advantageously, the hydrogen halide freed in the course of condensation is continuously neutralized by adding aqueous alkali metal hydroxides, alkali metal carbonates or alkali metal bicarbonates. For further reaction of the halotriazine dyes thus obtained, or for the reaction of the 2,4,6-trihalo-s-triazine with the compounds of the formula (34), the free amines or salts thereof, preferablly in the form of the hydrochloride, are used. The reaction is carried out at temperatures between about 0° and 40° C., preferably between 5° and 25° C., in the presence of acid-binding agents, preferably sodium carbonate, within a pH range from 2 to 8, preferably 5 to 6.5. 
     The condensation of the halotriazine with a compound of the formula (34) can be carried out before or after the condensation of the halotriazine with a dye of the formula (31). The condensation of the halotriazine with a compound of the formula (34) is preferably carried out in aqueous solution or suspension, at low temperature and at weakly acid or neutral pH. Here, too, the hydrogen halide freed in the course of the condensation is advantageously neutralized by uninterrupted addition of aqueous alkali metal hydroxide, alkali metal carbonates or alkali metal bicarbonates. 
     The diazotization of the diazo components, or of the intermediates containing a diazotizable amino group, is effected in general by the action of nitrous acid in aqueous mineral acid solution at low temperature. The coupling onto the coupling component takes place at strongly acid, neutral or weakly alkaline pH. 
     The reactive dyes of the formula (1) are suitable for dyeing and printing a very wide range of materials, such as silk, leather, wool, polyamide fibres and polyurethanes, and in particular cellulose-containing fibre materials of any kind. Such fibre materials are for example the natural cellulose fibers, such as cotton, linen and hemp, and also cellulose pulp and regenerated cellulose. The reactive dyes of the formula (1) are also suitable for dyeing or printing hydroxyl-containing fibres which are present in blend fabrics, for example mixtures of cotton with polyamide fibres or in particular polyester fibres. 
     The dyes according to the invention can be applied to the fibre material and fixed on the fibre in various ways, in particular in the form of aqueous dye solutions and print pastes. They are suitable not only for the exhaust method of dyeing but also for dyeing by the padding method, whereby the material is impregnated with aqueous, optionally salt-containing dye solutions and the dyes are fixed after an alkali treatment or in the presence of alkali, if desired by heating. After fixing, the dyeings and prints are thoroughly rinsed with cold and hot water, in the presence or absence of an agent which has a dispersing action and promotes the diffusion of the unfixed portions. 
     If the reactive dyes of the formula (1) in which D is the radical of an anthraquinone dye are insufficiently soluble in the alkaline dyeing liquor, this defect can be remedied in a manner known from the literature, namely by adding dispersants or other non-coloured compounds, for example a naphthalenesulfonic acid/formaldehyde condensate or in particular anthraquinone-2-sulfonic acid. 
     The reactive dyes of the formula (1) are distinguished by high reactivity and good fixing properties and very good build-up. They can therefore be used for exhaustive dyeing at low dyeing temperatures and require only short steaming times in the pad-steam process. The degrees of fixation are high, and the unfixed portions can easily be washed off, the difference between the degree of exhaustion and the degree of fixation being remarkably small, i.e. the soaping loss being very small. The reactive dyes of the formula (1) are also suitable for printing, in particular on cotton, but also for printing nitrogen-containing fibres, for example wool, silk or wool- or silk-containing blend fabrics. 
     The dyeings and prints prepared with the dyes according to the invention on cellulose fibre materials have a high tinctorial strength and high fibre-dye bond stability, not only in the acid but also in the alkaline range, and also a good light fastness and very good wet fastness properties, such as wash, water, seawater, cross-dyeing and perspiration fastness properties, and also a good pleating fastness, hot press fastness and rub fastness. 
     The examples which follow serve to illustrate the invention. The temperatures are given in degrees celsius, and parts and percentages are by weight, unless otherwise stated. Parts by weight relate to parts by volume as the kilogram relates to the liter. 
    
    
     The preparation of the monoazo or disazo intermediate compounds has not been described in all cases in the working examples below, but it will be readily apparent from the general description. 
     EXAMPLE 1

After the diazotization has ended, a small excess of nitrous acid is destroyed by addition of sulfamic acid. An aqueous solution containing 24 parts of the sodium salt of 2,6-dihydroxy-3-sulfomethyl-4-methylpyridine is then poured into the suspension of the diazo compound. The diazo compound dissolves to form a clear yellow dye solution. This solution is brought to pH 7, and a neutral aqueous solution of 21 parts of the sodium salt of 1,3-phenylenediamine-4-sulfonic acid is then added. The condensation reaction is carried out at 20°-25° while the pH of the solution is maintained at 6-7 by dropwise addition of sodium hydroxide solution. After the condensation has ended, the mixture is cooled down to 0° and is admixed with a solution of 18.5 parts of cyanuric chloride in 50 parts of acetone.
