Abstract

A disazo dye is obtained by combining p-diazobenzene-azo-salicylic acid with a b -naphthylamine sulphonic acid, such as the 2 : 5 or 2 : 6 monosulphonic acid or the 2 : 3 : 6 disulphonic acid. The p-diazobenzene-azo-salicylic acid may be prepared by combining diazotized p-nitraniline with salicylic acid, reducing the nitro group and diazotizing the amino group formed. The product dyes cotton or wool red shades in acid baths; the dyeing on wool may be chromed.
