     Examples of radicals D are those from the monoazo, polyazo, metal complex, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone or nitroaryl series. A particularly suitable radical of an organic dyestuff is one containing one or more water-solubilising groups, in particular sulpho groups. 
     For the alkyl, aryl, aralkyl, hetaryl, alkoxy, halogen and acylamino radicals mentioned in the present application and for the bridging members the following applies: 
     Alkyl groups are understood to mean in particular those having 1 to 4 C atoms, with or without the substituents, for example halogen, such as Cl or Br, OH, CN or OSO 3  H. 
     Aryl groups are understood to mean in particular phenyl radicals, with or without substituents, for example halogen, such as Cl and Br, C 1  -C 4  -alkyl, C 1  -C 4  -alkoxy, C 1  -C 4  -alkylsulphonyl, NO 2 , CN, CF 3 , SO 3  H, COOH. 
     Aralkyl radicals are understood to mean in particular benzyl radicals, with or without the substituents mentioned for the phenyl radicals.

     Examples of suitable bridging members W are: ##STR4## in which R 1  represents hydrogen or alkyl, and alkylene denotes an alkylene radical having 1 to 6 C atoms. 
     Alkylene radicals are --CH 2  --, ##STR5## --(CH 2 ) 3  --, --(CH 2 ) 4  --, --(CH 2 ) 6  --. 
     Examples of suitable aliphatic bridging members B are ##STR6## 
     The present invention furthermore relates to the preparation of the reactive dyestuffs of the formula (I) by methods known per se: 
     a) either by condensation of dyestuffs of the formula ##STR7##  in which D, W, R 1  and n have the abovementioned meaning, ps with n mol of trihalogenotriazines of the formula ##STR8## in which X&#39; is F, Cl to give compounds of the formula ##STR9##  and further condensation of the compounds of the formula (IV) with n mol of the components of the formula ##STR10##  in which R 2 , R, B and Z have the abovementioned meaning, or 
     b) in reverse order, by condensation of trihalogenotriazines of the formula (III) with the components of the formula (V) to give the primary condensation products ##STR11##  in which X&#39;, R 2 , R, B and Z have the abovementioned meaning, and further condensation with n mol of the compounds of the formula (VI) with the dyestuffs of the formula (II), or 
     c) by condensation of suitable precursors with trihalogenotriazines (III) and the components of the formula (V) or by condensation of suitable precursors with the primary condensation products of the formula (VI), followed by dyestuff synthesis, and 
     d) if desired, by exchange of the halogen atom X&#39; for the radical of pyridine-3-carboxylic acid in the synthesised halogenotriazine dyestuff. 
     The condensations of the starting components with the trihalogenotriazines are carried out irrespective of the order in aqueous or organic-aqueous media in the presence of acid-binding agents. Depending on the nature of the starting components, the first step of the condensation is carried out in pH ranges of 2 to 8, preferably 3 to 7, and at temperatures of 0° to 40° C., preferably 0° to 25° C. 
     Exchange of the second halogen atom of the triazine is completed in the pH range of 4 to 10, preferably 5 to 9, and in the temperature range of 0° to 60° C., preferably 0° to 30° C. 
     Examples of acid-binding agents are carbonates, hydroxides or phosphates, such as sodium carbonate, sodium bicarbonate, dilute sodium hydroxide solution, di-or trisodium phosphate or sodium fluoride. 
     If it is desired for the condensation or the dyestuff synthesis to lead directly to a dyestuff solution or to a liquid dyestuff preparation, the use of lithium carbonates or lithium hydroxide may be advantageous, if appropriate in combination with solubilising agents and/or stabilising buffer systems. Other conversion reactions of the dyestuffs or their precursors, such as metallisation reactions, sulphonations or introduction of acylamino groupings can in general be carried out in any desired steps of the dyestuff syntheses. 
     Particularly valuable dyestuffs of this series are water-soluble azo, formazan, anthraquinone, triphendioxazine and phthalocyanine dyestuffs, and in particular those having sulpho and/or carboxyl groups. The dyestuffs can be either metal-free or metal-containing, their preferred metal complexes being the copper, nickel, chromium and cobalt complexes. 
     Suitable dyestuff radicals D or amino-containing dyestuffs underlying the dyestuffs of the formula (I) are described in the literature in very large numbers. Examples are:

     Preferred dyestuffs are those of the formulae (VII) to (XXIII) below, in which in general A contains a radical of the formula ##STR12## and X, R 2 , R, B and Z have the abovementioned meaning.

     The reactive dyestuffs of the formula (I) are suitable for the dyeing and printing of the wide range of substrates, such as silk, leather, wool, synthetic polyamide fibres, but in particular of cellulose-containing materials of fibrous structure, such as linen, cellulose, regenerated cellulose and in particular cotton. They are suitable not only for the exhaust method but also for the dyeing by the customary pad-dyeing processes, in which the material to be dyed is impregnated with aqueous and, if desired, also salt-containing dyestuff solutions, and the dyestuffs are fixed after an alkaline treatment or in the presence of alkali, if desired with the application of heat. 
     The reactive dyestuffs of the formula (I) are distinguished by high reactivity and excellent fixation properties. Owing to their bifunctionality, they give high fixation yields even from a long liquor. They are characterised by a relative independence of the yield from the dyeing temperature and can therefore be used in the exhaust method at low to medium dyeing temperatures. In the pad-steaming process, they require only short steaming times. They produce dyeings of high colour strength and good light and wet fastness properties.

     24.2 g of the aminoazopyrazolone of the formula ##STR178## (prepared by coupling diazotised 2-amino-4-formylaminobenzenesulphonic acid onto 1- (4&#39;-sulphophenyl) -3-carboxy-5-pyrazolone and hydrolysis using dilute sodium hydroxide solution) are dissolved in 600 ml of water in the form of the sodium salt. The mixture is cooled to 0° to 2° C., the pH is brought to 5.0 with dilute hydrochloric acid and 4.0 ml of cyanuric fluoride are immediately added dropwise over a period of about 5 minutes. During this, the pH is constantly maintained between 4.3 and 4.6 with 2N sodium carbonate solution. When the reaction is complete after 15 minutes, a neutral solution of 18.6 g of the compound of the formula ##STR179## in 100 ml of water is added at 0° to 5° C. During this, the pH is maintained at 5.5 to 6 with 2N sodium carbonate solution, and the temperature is allowed to rise to 20° C. after 2 hours. 
     The dyestuff obtained of the formula ##STR180## dyes cotton from long liquor in greenish yellow hues with a high fixation yield.

After cooling to 0° C., 4.1 ml of cyanuric fluoride are run in, and the pH is maintained at 4.5 with 2N sodium carbonate solution. Stirring under the same conditions is continued for 15 minutes, and a neutral solution of 21.3 g of the component of the formula ##STR198## in 55 ml of water are then added.

     EXAMPLE 70 
     40 g of 1-amino-4-(2&#39;-aminomethyl-4&#39;-methyl-6&#39;-sulphophenylamino)-anthraquinone-2-sulphonic acid are dissolved in 800 ml of water and 100 ml of acetone by neutralisation with about 45 ml of 2N sodium hydroxide solution at a pH of 7. 
     The mixture is cooled to 10° C. and a solution of 17.5 g of cyanuric chloride in 100 ml of acetone is added dropwise over a period of 15 to 20 minutes. During the dropwise addition, the pH in the reaction mixture is maintained at 6.0 to 7.0 with 2N sodium carbonate solution. When sodium carbonate consumption has come to a standstill about 1 hour after the addition of cyanuric chloride, a neutralised solution of 39.7 g of the compound of the formula ##STR238## in 100 ml of water are run in at 20° C., and the pH is maintained at 6.5 with sodium carbonate solution. After condensation is complete, the dyestuff is either salted out or isolated by evaporating the solution in vacuo at 35° to 40° C., resulting in a salt-containing product. The dyestuff of the formula ##STR239## can be used for printing or dyeing of cellulose fabric by the continuous method and produces clear reddish blue shades. Very good fixation yields are obtained (λ max  =624 and 587 nm, in H 2  O). 
     EXAMPLE 71 
     53.1 g of 1-amino-4-(3&#39;-amino-5&#39;-sulpho-2&#39;,4&#39;,6&#39;-tri-methylphenylamino)-anthraquinone-2-sulphonic acid are dissolved in 530 parts of water at a pH of 6. 
     19.4 g of cyanuric chloride are dissolved in 100 ml of methyl ethyl ketone and the solution is poured onto 100 g of ice. The dyestuff solution is then added dropwise to the cyanuric chloride suspension at 0° to 10° C., and the pH in the reaction mixture is maintained at 4.5 with 10% strength sodium carbonate solution. After conversion is complete, a neutralised solution of 47 g of the compound of the formula ##STR240## in 130 ml of water is added at 20° to 25° C. and the pH is maintained at 5.8 to 6.0 with sodium carbonate solution until condensation is complete. The dyestuff obtained of the formula ##STR241## produces, by printing and continuous dyeing processes, on cotton clear, reddish blue shades with a very high fixation yield. 
     EXAMPLE 72 
     14.7 g of 1-amino-4-(3&#39;-aminophenylamino)-anthraquinone-2,4&#39;-disulphonic acid are dissolved in 250 ml of water at a pH of 5 and 0° to 5° C. 2.8 ml of cyanuric fluoride are added dropwise to the solution of the dyestuff component over a period of 5 to 10 minutes and the pH is maintained at 4.2 to 4.7 with 2N sodium carbonate solution. Stirring is continued for a short time, after which condensation to give the difluorotriazinyl dyestuff is complete. 
     A neutralised solution of 13.2 g of the compound of the formula ##STR242## in 50 ml of water is then slowly added to the solution of the reactive dyestuff component, while maintaining the pH at 5.0 to 5.6. The pH is then maintained at 6.0 to 6.5 and the temperature is allowed gradually to increase to 20° C. over a period of 15 hours, after which condensation is complete. The dyestuff solution is then salted out over a period of 2 hours. The precipitated dyestuff of the formula ##STR243## is filtered off with suction and washed with salt solution until the run-off is clear. Drying in vacuo at 45° C. gives a product which can be used to dye and print cellulose fabric in blue hues and with a high fixation yield. 
     EXAMPLE 73 
     18.0 g of the component of the formula ##STR244## are brought to a pH of 4.0 in 80 ml of water. 1.9 g of sodium fluoride are added to the solution, and the mixture is cooled to 0° to 20° C. 4.2 ml of cyanuric fluoride are then run in with further cooling, and the pH is maintained between 4.0 and 4.5 with sodium carbonate solution. About 15 minutes after the cyanuric fluoride addition, conversion is complete. The solution is then brought to a pH of 4.5 to 5.0. A neutralised solution of 19.0 g of 1-amino-4-(3&#39;-amino-2&#39;-methylphenylamino)-anthraquinone-2,5&#39;-disulphonic acid in 350 ml of water is then added dropwise to the reactive component obtained over a period of 30 minutes. During this, the temperature in the reaction solution is further maintained at 0° to 5° C. and the pH is maintained at 6.0 to 6.5 with sodium carbonate solution. After 2 hours, the temperature is allowed gradually to increase to 10° C. over a period of 15 hours. After condensation is complete, the dyestuff of the formula ##STR245## is salted out from the solution with sodium chloride, filtered off with suction, washed with 20% strength sodium chloride solution and dried at 45° C. in vacuo. 
     The dyestuff produces, on cotton, blue dyeings and prints with a high fixation yield. 
     Further blue anthraquinone dyestuffs having similar properties are obtained by condensing the anthraquinone components listed below of the general formula ##STR246## with the trihalogenotriazines and sulphatoethylsulphonylalkoxyanilines by one of the methods described above.

The solution is added dropwise over a period of 30 minutes to a suspension obtained by pouring a solution of 5.6 g of cyanuric chloride in 45 ml of acetone onto 45 g of ice. 
     The pH in the reaction mixture is maintained at 7.0 to 7.5 by adding 2N sodium hydroxide solution and the temperature is maintained at 0° to 5° C. Stirring is continued for 1 hour, after which the solution is clarified and 10.3 g of 2-[3-(2-sulphatoethylsulphonyl)-propoxy)-5-aminobenzenesulphonic acid are added to the filtrate in portions. 
     During the addition and later on, the pH in the reaction mixture is maintained at 6.0 to 6.5 and after the addition the temperature is increased to 20° to 25° C. After condensation is complete, the dyestuff is salted out from the solution with sodium chloride, filtered off with suction and dried at 40° to 50° C. in vacuo.

     EXAMPLE 114 
     36.7 g of the amino-disazo compound prepared in the known manner of the formula ##STR365## are dissolved in 400 ml of water at a pH of 6.0. After cooling the solution to 0° C., 5.0 ml of cyanuric fluoride are swiftly added dropwise and the pH is maintained at 4.5 to 5.0 with 2N sodium carbonate solution. 
     After this first condensation step is complete, 19.1 g of 4-[3-(2-sulphatoethylsulphonyl)- propoxy)-aniline are added and the pH is maintained at 5.5 to 6.0 with sodium carbonate solution. Stirring at 0° to 5° C. is continued for 2 hours, and the temperature is then allowed to rise to 20° C. with further pH control. The dyestuff obtained of the formula ##STR366## is salted out with sodium chloride, filtered off with suction and, after buffering at a pH of 6, dried at 45° C. in vacuo. It dyes cotton, by the processes known for reactive dyestuffs, with a high yield in brown hues.

     50.3 g of the aminoazo compound of the formula ##STR382## are dissolved in 400 ml of water at a pH of 6. The solution is cooled to 0° to 2° C., and 9.3 ml of cyanuric fluoride are added dropwise over a period of a few minutes. During this operation, the pH is maintained at 4.5 with 2N sodium carbonate solution, and stirring of the mixture under the same conditions is continued for a short period. When sodium carbonate consumption has come to a standstill, a solution of 35.4 g of 4-[3-(2-sulphatoethylsulphonyl)-propoxy)-aniline in 180 ml of water brought to a pH of 6 with 10% strength lithium hydroxide solution is run in, and the pH in the reaction mixture is maintained at 5.5 to 6.0. After 3 hours, the temperature is allowed gradually to increase to 20° C., and the dyestuff obtained of the formula ##STR383## is isolated by salting it out and filtering it off with suction. Gentle drying gives a powder which dyes cotton by the customary methods with a high yield in scarlet hues.

     22.1 g of the triphendioxazine compound of the formula ##STR448## are dissolved in 300 ml of water by adding sodium hydroxide solution at a pH of 11.5-12. 
     This solution and that of the reactive components prepared above are added dropwise simultaneously to 80 ml of initially introduced ice water, and the pH in the reaction mixture is maintained at 8-8.5 with 2N sodium hydroxide solution and the temperature is further maintained at 0°-2° C. After several hours, conversion is complete. The temperature is allowed to rise to 20° C. overnight. The dyestuff is salted out, filtered off with suction and, after buffering to a pH of 6.7, dried at 45° C. in vacuo. It has the formula ##STR449## and dyes cotton by the customary methods in strong blue shades with high fixation yields.

To complete the reaction, the temperature is raised to 20° C. over a period of 2 hours and the pH is further maintained within the above limits until consumption of the neutralising agent has come to a standstill. A neutralised solution of 20.8 g of 5-amino-2-[3-(β-sulphatoethylsulphonyl)-propoxy)-benzenesulphonic acid in 80 ml of water is then added to the primary condensation product and the pH is further maintained at 6.0 to 6.5 with lithium hydroxide.

The mixture is cooled to 0°-30° C., and 7.4 g of cyanuric fluoride are added dropwise to this solution over a period of a few minutes. During the dropwise addition, the pH is maintained at 4.5-5.0 with 2N sodium carbonate solution. Stirring is continued for another quarter of an hour, after which a neutralised solution of 23.0 g of the compound of the formula ##STR525## in 100 ml of water is added to the primary condensation product, and the pH in the reaction mixture is maintained at 5.0-6.0 with sodium carbonate solution. When sodium carbonate consumption has gradually come to a standstill, the temperature is allowed to rise to 20° C. After conversion is complete, the dyestuff of the formula ##STR526## is salted out, isolated, and, after buffering to a pH of 6, dried at 45° C. in vacuo.

After condensation is complete, the reactive dyestuff obtained is salted out, filtered off with suction and, after buffering to a pH of 6.5, gently dried in vacuo. Using the dark powder obtained, cotton is dyed in greenish grey hues. 
     If a 1:1 mixture of the chromium complex and the corresponding cobalt complex is used instead of the abovementioned pure chromium complex, a dyestuff mixture is isolated which dyes cotton in neutral grey or black hues having good light fastness properties.

Stirring is continued for a short period, after which a neutral solution of 22.0 g of 5-amino-2-[3-(β-sulphatoethylsulphonyl)-propoxy]-benzenesulphonic acid in 80 ml of water cooled to 0° C. is added, and the pH is maintained at 5.5-6.0 overnight. After condensation is complete, a diazonium salt suspension obtained in the usual manner by diazotisation of 8.7 g of 2-aminobenzenesulphonic acid is added, and coupling is completed by addition of sodium carbonate at a pH of 6.5-7 first at 0° C. for several hours and later on with an increase to 20° C. The dyestuff obtained of the formula ##STR570## is isolated and dried. It produces on cotton, from a long liquor, strong red dyeings having good light and wet fastness. 
     EXAMPLE 178

The solution is cooled to 0° C., and 6.9 g of cyanuric fluoride are slowly added dropwise. The pH is maintained at 6.0-6.5 with sodium bicarbonate solution. When the reaction is complete after a few minutes, a neutral, cooled solution of 21.8 g of 5-amino2-[3-(β-sulphatoethylsulphonyl)-propoxy]-benzenesulphonic acid in 80 ml of water is added, and the pH is further maintained at 6.5 with sodium carbonate solution.

     Running 100 g of the above oil into 250 ml of 96% pure sulphuric acid at 0°-3° C., stirring the mixture at 0° C. for a few hours, stirring it into 1.8 kg of ice, liming the solution with 410 g of CaCO 3  up to a pH of 4.7, filtering off the calcium sulphate and concentrating the solution in vacuo down to 500 ml gives a solution of the substance of the formula ##STR579## which is suitable for synthetic purposes and whose content can be determined by titration with sodium nitrite. 
     If the above amino-β-hydroxyethylsulphonyl-alkoxybenzene is run into 20% strength oleum instead of 96% pure sulphuric acid, the mixture is stirred until it is completely sulphonated and sulphated at 20° C., suitable workup gives the solution of a compound of the formula ##STR580## which, determining its content, can also be used for synthetic purposes. 
     EXAMPLE 181 
     80.0 g of the compound of the formula ##STR581## prepared by the procedure given in European Patent 0,355,492 are stirred into 160 ml of 96% pure sulphuric acid at 0° C. The mixture is allowed to reach 20° C. over a period of 1 hour, the solution is poured onto 800 g of ice and 320 ml of water, the prism-like crystals, after additional stirring for a short period, are filtered off with suction and the adhering sulphuric acid is displaced by washing with isopropanol. The product can be dried at 50° C. in vacuo. It has the formula ##STR582## 
     If the above compound is stirred into 20% strength oleum instead of into 96% pure sulphuric acid, and the product is then worked up, as described in Example 180, by adding CaCO 3  to the aqueous sulphuric acid solution, the solution of a compound of the formula ##STR583## is obtained, which, after determining its content, can also be used for dyestuff syntheses. 
     EXAMPLE 182

The reaction product of the formula ##STR585## can be precipitated from the mixture obtained by dilution with 5 l of water in the form of a yellow oil. 
     The intermediate can either be converted directly without isolating it or after dissolving it again in 1,000 ml of ethanol or acetonitrile to the thioether ##STR586## using 156 g of 2-mercaptoethanol and 276 g of potassium carbonate at 60°-80° C. and this thioether can be oxidised in the known manner after the dilution of the solution with 3 l of water and addition of 4.5 g of sodium tungstate at 55°-60° C. and 35% strength H 2  O 2 . The nitrosulphone obtained of the formula ##STR587## is reduced, in the manner described in Example 179, catalytically to give the amino compound, which can then be either sulphated or sulphated and sulphonated. 
     The corresponding m and p compounds can be prepared analogously from m- or p-nitrophenol and 1,3-bromochloropropane.
