Abstract

Azo dyes, insoluble in water, are made in substance or on the fibre by coupling a diazotized Bz-1-aminobenzanthrone with a suitable coupling component. In examples the following components are specified; Bz-1-aminobenzanthrone and its 2-methoxy- and ethoxy derivatives; the m-nitranilide, anilide, a - and b -naphthylamide, o-toluidide, 2 : 4-dimethoxy - 5 - chloranilide and 2 - methyl - 4 - methoxyanilide of b -oxynaphthoic acid, the p-chloranilide of 2-oxycarbazole-3-carboxylic acid (see Specification 343,164), the p-anisidide and 2-methyl-4-methoxyanilide of 1 : 2-1<1> : 2<1>-benzocarbazole - 5<1> - oxy - 4<1> - carboxylic acid (obtained according to Specification 347,113), the o-toluidide of 2-oxyanthracene-3-carboxylic acid (cf. Specification 367,907), diacetoacetyl-o-tolidine.
