As the third auxiliary component, instead of a benzene compound, some amnno-naphthol sulfonic acid or its derivative is used. Example 1. -Azo compound from 30.3 parts of 2-ayio-naphthalene-4,8-yes of sulphonic acid and 14.5 parts of 1-amnonaphthalene after dnozotizing mixed with hydrochloric acid solution 9.5 parts -amino-methylbenzene. With an atom in order to bind hydrochloric acid, the solution of acetic acid E3O3 sodium is added slowly, stirred until the next day, then diazotnuyut, at 0 ° hydrochloric acid, including nitrous acid sodium nitrate. After a few. hours of stirring, separate the diazocompound from the solution, mix it again with 1200 parts of ice water, add ..

hydrochloric acid solution of 8.5 parts of 3-amino1-methyl-6benzene, and a solution of 40 parts of crystalline sodium acetate is poured. Allow to stand, stirring until the next di, diazotized by adding hydrochloric acid and sodium nitrate, squeeze after four hours of mixing the diazo compound, mix it again with 1200 parts of ice water and pour it into a warm solution prepared from 12 hours. 4-nitro-1: 3-diami o-benzene in 12 parts of hydrochloric acid 23 Be and 300 parts of water. Leave to stand, stirring until the next day, gradually being heated to 60, neutralized with soda until alkaline, and the dye is salted. He paints cotton paper in clean reddish-brown tones.

Example 2. - Diazocompound dye, resulting from 29.7 hours. 1-amino-benzene-2,4-disulfite acid sodium with a combination of diazo compounds with 10.8 h. 3-amino-1-methyl-benzene, salted off and sucked away. Then it is mixed with 500 parts of ice water and I combined with 11 hours. 3-amino1 4-methoxy-1-methyl-benzene dissolved in 10 parts of hydrochloric acid, 23 ° Be and 100 parts of water. And a slow reflux of a solution from 30 parts of crystalline vinegar 1 layer of sodium in 60 parts of water. After stirring the next day, the solution is heated to 50 and the diazo coloring agent is dissolved by adding 25 parts of 40% sodium hydroxide, then cooling and diazotization with sodium nitrate, which is taken in an amount of 6 parts, in the presence of 60 parts of hydrochloric acid, with the temperature should not exceed 5 °. Received by salting out and pressed diazocompound are added to 400 parts of water with ice, and then it is combined with 6 hours of 3-amino 1-methyl-benzene dissolved in 5 hours. hydrochloric acid 23 ° Wb and 50 parts of water, with a slow setting of 20 parts sodium acetate and a temperature of 5 °. Stirring continues until the next day. After the WTO, the mass is heated to 50, 40 parts of hydrochloric acid 23 ° Bd are added and the azo-solvent is separated from the solution. It is dissolved at 60 using 3 parts of sodium carbonate in 600 parts of water. The solution is filtered, cooled to 8 and mixed in order to diazotize with 25 parts of hydrochloric acid and nitrite. Then it is combined with three parts of 4-nitro-1,3-benzene benzene dissolved in 12 parts of hydrochloric acid 23 ° Be and 250 parts of water. The last solution is kept warm. The next day, slowly heated to 60, neutralized with soda until alkaline, and the dye is salted. He paints cotton b-magu in brown.

Example 3. - The diazocompound used in Example 2 is combined with slow production of 11 parts of sodium acetate with 16.6 parts of 1-amino-naphthalene-6-sulfonic acid taken in solution 250 parts of water with 8 including sodium carbonate. When heated to 50, the diazo dye is dissolved by adding sodium hydroxide, then diazotized at B 5.3 parts of sodium nitrate in the presence of hydrochloric acid. The diazocompound is combined with a slow trickle of sodium acetate 11 with 8 hours. 3-amino-1-methyl-benzene dissolved in 11 parts of hydrochloric acid and 100 parts of water. The next day, the resulting acidic dye is isolated by adding hydrochloric acid and salinization with sodium chloride. It is filtered and dried in 600 parts of water with the addition of 8 parts of sodium carbonate at 60. The filtered and cooled solution is mixed with 45 parts of hydrochloric acid then obtained under the action of 3.5 parts of nitrite sodium diazocompound stirred with warm p shots on 7.6 h. 4-nitro-1-3-diamino-benzene in 12 hours. The hydrochloric acid 3o 23 ° and 250 h. of water. Ready dye prepared as reception indicated in the previous example.

Example 4. - Azo-compound for 30.3 hours. 2-amino-naphthalene-4,8-disul

photoacids and 14.4 parts of 1-amino-naphthalene after diaoseation are combined with 22 parts of 1-amino-naphthalene-b-sulfonic acid in the presence of sodium acetate. The diazo dye is dissolved by soda, again separated from the solution in the cold with hydrochloric acid and then diazotized with 6 parts of sodium nitrate. Then combine with 21.5 hours; 2-amino-8-oxnaftaln-6-sulfonic acids in alkaline soda solution. The obtained trisazocrashite, which is isolated by salting and filtration, is again dissolved and diazotized in the presence of hydrochloric acid with 5 parts of sodium nitrite, and then combined with a warm solution of 11 parts of 4-H11tro-1,3-diaminobenzene in 18 hours acids and 250 parts of water, left at the same time until the next day, removing excess salt by slow addition of sodium acetate, bringing the temperature gradually to 60. After the completion of the combination, neutralize until alkaline with sodium carbonate and dye the salt. He paints cotton paper in olive-green color. . Example 5. - A diazo compound of a mono-azo dye obtained by combining a diazo compound from 29.7 and 1-amino-benzene-2,4-sodium disulfonic acid with 14.4 parts of 1-amino-naphthalene is combined to obtain a diazo dye with 22.3 hours 1-amino-naphthalene-sulfonic acid. From it, the diazocompound is transferred, - to diazothir 7 parts of sodium nitrite in the presence of hydrochloric acid, it is salted out and filtered off. Then it is mixed again with water and ice and introduced into an alkaline soda solution of 19.1 parts of 2-ayino-8-hydroxy-naphthalene 6-sulfonic acid. The resulting tris-azo dye is separated from the alkaline solution, diazotized again and then mixed with a solution of 8.8 parts of 4-nitro-1,3-diamino-benzene in 15 parts of hydrochloric acid 23 ° Be and 200 parts of water. In the final form, tetrakis-azo dye is obtained according to the method of Example 1; he paints cotton paper in olive-color. Priysr 6. - Diazosoedunnenzh mono-azo dye, obtained by combining a diazo compound of 20, S h. 4-chloro -1 - ampo-benzene - 2 - sulfonic acids with 14.4 parts of 1-amino-naphtha.iia are combined to obtain a diazo dye with 22 , 3 h. 1-amino-naphthalene-b-sulfonic acids. After salting out {1 and filtering off as the sodium salt, the dye is diazotized once again with 5 parts of sodium nitride in the presence of hydrochloric acid. The diazo compound thus obtained is introduced into an alkaline soda solution of 24.8 parts of 2-amiko-8-hydroxy-naphthat lin-3,6 - disulfonic acid (monosodium salt), Tris-azo-dye is separated, dissolved in water and diazotized . 4.2 parts sodium nitrite in the presence of hydrochloric acid. The diazo compound is poured into a solution of 9.3 parts of 4-nitro-1,3-diamino-benzene in 16 parts of hydrochloric acid 23 ° B6 and 250 parts of water and otherwise proceeds as indicated in Example 1. The dye dyes cotton. paper in olive green. As the initial and first and second auxiliary components, other corresponding compounds are used instead of those given in the examples. Instead of the third subsidiary. the components should be used, in addition to the amino-oxy-naphthalic-sulphonic acids mentioned, their isomers, or other derivatives capable of combination and diazotipylation, such as: amhishu - arnl-aiino-oxy-naphthalene-sulphonic} slots.
