Abstract

A new series of reactive dyes containing formyl group were prepared by diazotizing 2-amino-4-chloro-5-formylthiazole and coupling with γ-acid i.e., naphthionic acid. Bisazo dyes based on H-acid were prepared. The dyes were applied on wool, silk and nylon and their fastness properties were measured.
