Abstract

1,242,047. Azo dyestuffs. CIBA-GEIGY A.G. 31 Jan., 1969 [2 Feb., 1968], No. 5344/69. Heading C4P. [Also in Division G2] The invention comprises azo dyes of the formula wherein A is a naphthalene residue attached at the 1-position to the azo group, at the 2-position to an amino group and in 8-position to a hydroxyl group and contains at least one sulphonic acid or sulphonamide group in 6-position; B is a naphthalene residue containing one or two sulphonic acid or sulphonamide groups; n is 1, 2, 3 or 4 and D is an n-valent acyl residue of an at least n-valent acylating agent, e.g. the group -CO-, -CS-, a diacyl residue of a dicarboxylic acid such as terephthalic or isophthalic acid, fumaric acid, glutaric acid, thiophene-2 :5- dicarboxylic acid, an azobenzene dicarboxylic acid or a cyanuric chloride or a dichlorotriazine derivative. The dyes are made (1) by reacting an amine of the formula with a halide of the acylating agent, e.g. in Example A 1 , 2-nitro-6-aminonaphthalene-4:8- disulphonic acid # 2-amino-8-hydroxynaphthalene-6-sulphonic acid, the nitro group is reduced and 2 moles of the product reacted with terephthaloyl chloride; or (2) by coupling diazonium salts of the formula with compounds of the formula A-H, e.g. in Example O, the reaction product of two moles of 2-nitro-6-aminonaphthalene-4 :8-disulphonic acid with terephthaloyl chloride is reduced to the amine which is diazotized and coupled with 1 - hydroxy - 3 - pyrrolidinosulphonyl - 7 - aminonaphthalene. Other examples are given.
