Abstract
Azo dyes are made by coupling a diazotized or tetrazotized aromatic amine which is free from hydroxy groups with a compound of the general formula <FORM:0420508/IV/1> wherein X = O or S and R and R1 = H or aliphatic or cyclic radicles. In examples, dyes are produced in substance, on a substratum or on the fibre from the following components: o-nitraniline, 4-chloro-2-nitraniline, 4-methyl-2-nitraniline, 4-toluidine-3-sulphonic acid, aniline-o-sulphonic acid, 1-naphthylamine-4-sulphonic acid, 1-amino-2-methoxy- or 2-methyl-4-nitrobenzene, 1 -amino - 2 - methyl - 4 - chlorobenzene, 2 : 5-dichloraniline; barbituric acid, mono- and diphenyl-barbituric acids, mono-o- and p-chlorphenylbarbituric acid, di-o-tolylbarbituric acid, di-o-anisylthiobarbituric acid, mono-o- and p-tolylbarbituric acid, and a - and b -mono- and di-naphthylbarbituric acids. Greenish-yellow and red shades are obtained.
