     EXAMPLE 1 
     17.2 parts of 2-chloro-4-nitroaniline are diazotized in the conventional manner. A solution of 15.3 parts of 1-amino-2,5-dimethoxybenzene in 300 parts of water and 25 parts of 5-normal hydrochloric acid is run into the filtered nitrite-free diazonium salt solution, whilst stirring. As coupling proceeds, the reaction mixture becomes viscous; it is therefore diluted with about 1,000 parts of water. After completion of coupling, the dye is filtered off and washed neutral with water. The paste of the monoazo dye is stirred into a mixture of 600 parts of acetic acid and 12 parts of concentrated hydrochloric acid at from 50° to 60° C. The temperature is then lowered to 20°-25° C. by external cooling and a solution of 9.0 parts of sodium nitrite is added over from 5 to 10 minutes. After about 60 minutes, the excess nitrite is removed with amidosulfonic acid. A solution of 25.6 parts of 4-phenyl-2-(N-diallylamino)-thiazole in 40 parts of acetic acid is added to the filtered diazonium salt solution over 30 minutes. The pH is then raised to 2.5 with aqueous sodium acetate solution. After completion of coupling, the disazo dye is filtered off, washed first with isopropanol and then with hot water, and dried. The dye which has the following formula ##STR14## is very suitable for printing cotton or cotton/polyester union fabrics. Navy to black dyeings are obtained. 
     The dyes summarized in the Table which follows can be prepared by a method similar to that described in Example 1 and give dyeings have similar properties.

     EXAMPLE 23 
     20.7 parts of 2,6-dichloro-4-nitroaniline are introduced into a mixture of 40 parts of concentrated sulfuric acid and 30 parts of nitrosylsulfuric acid (of from 40 to 45% strength) at 10°-15° C., whilst stirring, and the diazotization is allowed to take place overnight at room temperature. The solution is then poured onto a mixture of 200 parts of ice and 200 parts of water. After having removed excess nitrite, a solution of 15.3 parts of 1-amino-2,5-dimethoxybenzene in 300 parts of water and 25 parts of 5-normal hydrochloric acid is added over about 30 minutes. As coupling proceeds, the reaction mixture becomes viscous; it is therefore diluted with about 700 parts of water. After completion of coupling, the dye is filtered off and washed nuetral with water. The filter cake of the monoazo dye is dissolved in 400 parts of acetic acid by stirring at room temperature and after adding 12 parts of concentrated hydrochloric acid the dye is diazotized with an aqueous solution of 8.0 parts of sodium nitrite. After about 3 hours at 20°-25° C. the diazotization is complete, and a solution of 25.6 parts of 4-phenyl-2-(N-diallylamino)-thiazole in 40 parts of acetic acid is added to the nitrite-free diazonium salt solution. Coupling is then completed by means of an aqueous solution of 10 parts of sodium acetate, at pH 3-4. The dye is filtered off and washed first with isopropanol and then with hot water. After drying under reduced pressure at 60° C., 46 parts of a dark powder having the following formula ##STR38## are obtained. This product is very suitable for printing cotton or cotton/polyester union fabrics. Navy to black dyeings are obtained. 
     The dyes summarized in the Table which follows can be prepared by a method similar to that described in Example 23 and give dyeings having similar properties.

     EXAMPLE 69 
     13.8 parts of p-nitroaniline are diazotized in the conventional manner. A solution of 15 parts of α-naphthylamine in 50 parts of acetic acid is allowed to run into the filtered nitrite-free diazonium salt solution, whilst stirring. As coupling proceeds, the reaction mixture becomes viscous. It is therefore diluted with about 400 parts of water. After completion of coupling, the pH is brought to 6-7 with 30% strength aqueous sodium hydroxide solution. The dye is filtered off and washed thoroughly with water. The paste of the monoazo dye is stirred thoroughly into a mixture of 800 parts of acetic acid and 12 parts of concentrated hydrochloric acid at 50°-60° C. The temperature is then lowered to 0°-10° C. by external cooling and a solution of 8.3 parts of sodium nitrite is added over 5-10 minutes. After about 30 minutes, the excess nitrite is removed with amidosulfonic acid. A solution of 26.6 parts of 2-(n-β-methoxycarbonylethyl-N-ethyl)-4-phenylthiazole in 60  parts of acetic acid is added to the filtered diazonium salt solution over 30 minutes. The pH is then raised to 2.5 with aqueous sodium acetate solution. After completion of coupling, the disazo dye is filtered off, washed first with isopropanol and then with hot water, and dried. The dye, which has the following structure ##STR81## is very suitable for dyeing or printing cotton or cotton/polyester union fabrics. Navy to black dyeings are obtained. 
     The dyes summarized in the Table which follows can be prepared by a method similar to that described in Example 1 and give dyeings having similar properties.

     EXAMPLE 135 
     18.3 parts of 2,4-dinitroaniline are introduced into a mixture of 29 parts of nitrosylsulfuric acid (containing 13.1% of dinitrogen trioxide) and 120 parts of 85% strength sulfuric acid at 0°-5° C., whilst stirring. After about 4 hours at 0°-5° C., the diazotization is complete and the solution is added dropwise, whilst stirring, to a solution of 15 parts of α-naphthylamine, 400 ml of water and 15 parts of concentrated hydrochloric acid, which is cooled to 0° C. by adding 400 parts of ice. Coupling is complete after 2-3 hours. The reaction mixture is neutralized with dilute sodium hydroxide solution, the product is filtered off and washed salt-free with water, and thereafter the procedure is continued as in Example 69. The resulting disazo dye, having the following composition ##STR149## dyes cotton, and cotton/polyester union fabrics, in lightfast greenish blue hues. 
     The dyes summarized in the Table which follows can be prepared by a method similar to that described in Example 135 and give dyeings having similar properties.
