Abstract

Azo dyes are made by coupling in an acid solution a diazo compound of o-aminodiphenyl-sulphone, or of a nuclear halogen, alkyl- or alkoxy-substitution product thereof, with 2-amino-8-naphthol-6-sulphonic acid. They dye wool from an acid bath red shades and have a good levelling power. Diazo compounds specified in examples are o-aminodiphenyl-sulphone, o-aminophenyl-p-tolylsulphone, 2-amino-4<1>-ethoxy-, methoxy-, ethyl-, chloro- or bromo - diphenylsulphone, 2 - amino - 5 - chlordi - phenylsulphone, 2 - amino - 2<1> - methyldiphenyl - sulphone and 2-amino-4-chloro-4<1>-methyldiphenylsulphone.
