Synthesis and dyeing characteristics of some new arylazopyrazole derivatives

Abstract

Abstract A variety of new arylazopyrazole derivatives were obtained by the coupling of diazotised 5‐amino‐4‐arylazopyrazoles with active methylene reagents and treatment of the resulting products with hydroxylamine hydrochloride. The behaviour of the newly synthesised products as acidic, direct and basic dyes on textiles is reported.
