Abstract
Azo dyes are made in substance or on a substratum, e.g. the fibre, by coupling a monodiazo-compound of 7 : 7<1> - diaminothioindigo with an acetyl- or aroyl-acetic acid arylide which does not contain any group rendering the dyestuff soluble in water. Green to olive-green shades fast to soaping and washing are obtained. In examples the production of green dyeings on cotton and of a dyestuff in substance using the following coupling components is described: diacetoacetyl-o-tolidine, acetoacetyl-p-amino-phenyl-benzimidazole or 4-methylbenzimidazole, benzoyl-acetic acid p-aminophenylbenzimidazole, benzoylacetic acid-o-chloranilide, p-methylbenzoyl - acetic acid-a -naphthylamide, p-methoxybenzoyl-acetic acid anilide, m-nitrobenzoyl-acetic acid-o chloranilide, b -naphthoyl-acetic acid anilide, acetoacetic acid - 2 - methoxy-4-chlor-1-anilide, terephthaloyl - bis-acetic acid - 4 - chloro - 2 - methoxyanilide, p-methylbenzoylacetic acid - 4 - methoxy - 1-anilide, p-chlorobenzoyl-acetic acid anilide, benzoyl-acetic acid-o-toluidide and dibenzoyl-acetic acid arylides. Specifications 210,217, 210,347, [both in Class 2 (iii), Dyes &c.], and 365,531 are referred to.
