The solution is cooled to -5.degree. -0.degree. and 21 parts of 4/normal sodium nitrite solution are added dropwise. The diazo solution is added dropwise over the course of 30 minutes to a solution consisting of 15 parts of N,N-diethylaniline, 5 parts of aminosulphonic acid, 50 parts of glacial acetic acid, and 25 parts of water. 100 parts of ice are added simultaneously to keep the temperature at 0 to 5.degree.. The solution is diluted with 160 parts of isopropanol and 100 parts of ice and the pH is adjusted to 5 by the addition of 110 parts of sodium acetate. Stirring is effected and a crystalline dye obtained. The dye is filtered with suction, washed twice, each time with 100 parts of water, and dried at 50.degree. under vacuum.
30.5 parts of the dried and finely ground dye are added to 300 parts of butanol, the mixture is stirred and 3.5 parts of magnesium oxide and 25 parts of dimethyl sulphate are added. The suspension is subsequently heated to 45.degree.-50.degree. over the course of 3 hours. After cooling to room temperature, the dye solution is shaken twice, each time with 150 parts of 26 % brine and concentrated by vacuum evaporation of 50.degree.-60.degree.. The residue is dissolved in 300 parts of water at 80.degree., 15 parts of "Hyflo" and 10 parts of "Norit Supra" are added and after 15 minutes it is filtered by means of a talc filter. The filtrate is washed with 750 parts of water of 50.degree. and the dye is salted out with 70 parts of sodium chloride. Stirring is effected and the crystalline dye is filtered with suction and washed with 100 parts of 5% aqueous sodium chloride solution.

After cooling to room temperature, the suspension is diluted with 150 parts of chloroform and filtered over Hyflo. The solvent is removed in a vacuum and the oily residue is taken up in 300 parts of water and 90 parts of ethanol and salted out with 15 parts of common salt.

18 parts of 2-amino-6-methoxybenzothiazole are dissolved in 100 parts of glacial acetic acid and 90 parts of sulphuric acid are added while cooling with ice so that the temperature does not exceed 35.degree.-40.degree.. 100 Parts of ice are subsequently added and a solution consisting of 7.3 parts of sodium nitrite and 25 parts of water is then added dropwise at -5.degree. to 0.degree.. The mixture is stirred for 1 hour with cooling and a solution consisting of 31.7 parts of the coupling component of the formula ##STR381## dissolved in 100 parts of glacial acetic acid and 50 parts of dimethylformamide, is added. The reaction mixture is stirred for 3 hours at room temperature and the pH is then adjusted to 3 with 170 parts of a 30% aqueous sodium hydroxide solution. The temperature is kept below 35.degree. by cooling. The precipitated dye is filtered and well washed with water and dried at 50.degree. in a vacuum. 25.5 Parts of the dried and ground dye are mixed while stirring with 200 parts of glacial acetic acid, 2.2 parts of magnesium oxide are added and the mixture is heated to 60.degree.-70.degree.. 14 Parts of dimethyl sulphate are added dropwise over the course of 15 minutes and the mixture is subsequently sitrred at 70.degree.-75.degree. for 3 hours. The reaction mixture is diluted with 2000 parts of water and the dye salted out by the addition of 15 parts of zinc chloride and 80 parts of sodium chloride.

27.5 Parts of 4-p-diphenoxymethylaniline are diazotized in the presence of 25 parts of 36% hydrochloric acid in 300 parts of water at 0.degree.-3.degree. C with 21 parts of 4/normal nitrite solution. The excess nitrite is decomposed after 30 minutes by the addition of amidosulphonic acid and the resulting diazonium solution clear filtered. 17.7 Parts of 1,3,3-trimethyl-2-methylen-2,3-dihydroindole are added dropwise at 3.degree.-5.degree. and then 150 cc of a 20% sodium acetate solution are added while cooling simultaneously in the course of 2 hours. The reaction mixture is heated to 10.degree.-15.degree., 20 parts of 30% sodium hydroxide solution are added and the coupling product is stirred for one hour. The red dye (azo base) is filtered with suction, washed with water and dried at 50.degree.-60.degree. at reduced pressure.
The methylation is effected by dissolving 36 parts of the azo base in 220 parts of chlorobenzene by the addition of 3.5 parts of triisopropanolamine. 40 Parts of the chlorobenzene are distilled off at 80.degree.-85.degree. under reduced pressure and 11.9 parts of dimethyl sulphate are subsequently added dropwise. The mixture is stirred at this temperature until the methylation is complete in accordance with thin layer chromatography. The mixture is cooled and the dye crystallizes, is suction filtered and washed with chlorobenzene. The dye agrees with the formula ##STR470## and dyes polyacrylonitrile fibres and polyester of polyamide fibres, modified by the introduction of acid groups, in golden-yellow shades. Replacing the above diazo component by 27.5 parts of 4-o-diphenoxymethylaniline, the dye of the formula ##STR471## is obtained in accordance with the same process. Applied on polyacrylonitrile fibres and polyester or polyamide fibres, modified by the introduction of acid groups, this dye gives golden-yellow dyeings.

application Example A
20 Parts of the salt of the dye described in Example 1 and 80 parts dextrin are ground for 4 hours in a powder mill. 1 Part of the preparation so obtained is made into a paste with 1 part 40% acetic acid, then 200 parts demineralized water are poured onto the paste and the mixture is boiled for a short time. (The same dye and dextrin mixture can also be formed into a paste with 100 parts water and finally be spray dried). The mixture is then diluted with 7000 parts demineralized water, mixed with 2 parts glacial acetic acid and is put into a bath at 60.degree. with 100 parts polyacrylonitrile fabric. The fabric may be pre-treated for 10 to 15 minutes at 60.degree. in a bath consisting of 8000 parts water and 2 parts glacial acetic acid.
The dyebath is raised to 98.degree. to 100.degree. over a period of 30 minutes, boiled for 1 1/2 hours and the fabric is rinsed. A bluish-red dyeing with good light and wet fastness properties is obtained.
10 Parts of the dye mentioned in Example 1 are dissolved in 60 parts glacial acetic acid and 30 parts water. A stable concentrated solution, with a dye content of about 10%, is obtained, which solution can be used to dye polyacrylonitrile according to the above-mentioned process.
Application Example B

With this solution the following dyeings are made:
a. The solution is diluted with 7000 parts of demineralized water and mixed with 21 parts of anhydrous sodium sulphate, 14 parts of ammonium sulphate, 14 parts of formic acid and 15 parts of a carrier, based on the reaction product of ethylene oxide with dichlorophenolene are put into a bath at 60.degree. with 100 parts of a polyester fabric, which fabric has been modified with acid groups. The fabric may be pretreated for 10 to 15 minutes at 60.degree. in a bath consisting of 8000 parts of water and 2 parts of glacial acetic acid.
The dyebath is raised to 98.degree.-100.degree. over a period of 30 minutes, boiled for 11/2 hours and the fabric rinsed. A similar bluish-red dyeing with good wet fastness is obtained.
b. The solution is diluted with 3000 parts of demineralized water and mixed with 18 parts of anhydrous sodium sulphate, together with 6 parts of ammonium sulphate and formic acid and put into the bath at 60.degree. with 100 parts of a polyester fabric, which fabric has been modified with acid groups. The closed vessel is heated to 110.degree. over a period of 45 minutes, kept at this temperature for one hour with shaking, cooled to 60.degree. within 25 minutes and the dyed fabric rinsed. A similar bluish-red dyeing with good wet fastness is obtained.
c. The same procedure as described in paragraph b) above is carried out except that the closed vessel is heated for one hour at 120.degree..
Formulae of representative dyes of the foregoing Examples are as follows:
