Abstract

330,349. Groves, W. W., (I. G. Farbenindustrie Akt.-Ges.). April 12, 1929. Azo dyes are made in substance or on a sub. tratum by combining any diazo, tetrazo or diazo. azo compound free from sulphonic or carboxylic . groups with a 6-amino-2-naphthol-3-carboxylic acid arylide of the general formula where Y = -NH2, -NH-aryl or .N< alkyl. Two series of dyestuffs are obtainable according to the coupling conditions used. The following components are specified : 6-phenylamino-2-naphthol- 3-carboxylic acid anilide or o-toluidide, 6-p-methyl (or chlor)-phenylamino-2 - naphthol - 3 - carboxylic acid-o-anisidide, 6-o-chlorphenylamino-2-naphthol- 3-carboxylic acid anilide, 6-p-chlorphenylamino-2- naphthol-3-carboxylic c acid-p-chloranilide, 6-N- methylphenylamino-2-naphthol-3-carboxylic acid. anilide and 6-amino-2-naphthol-3-carboxylic acidp-toluidide; diazo components specified are alphanaphthylamine, 4-chloro-o-anisidine, 5-chlor-otoluidine, p-nitraniline, m-nitro-p-toluidine, mnitro-o-anisidine, o-aminoazotoluene, alpha-aminoazotoluene, alpha-aminoanthraquinone, - dianiside, 2 : 5-dichloraniline, and 2 : 4 : 5-trichloraniline. 6-Amino-2-naphthol-3-carboxylic acid arylides are made from 6-amino-2-naphthol-3-carboxylic acids (c.f. Specification 326,971) or substitution products thereof according to Specification 23732/13.
