Preparation of Cationic Azo Dyes Derived from 2-Amino-6-(2-chloroethoxy)benzothiazole and 2-Amino-4-(2-hydroxyethoxy)benzothiazole

摘要

Azo dyes derived from 2-amino-6-(2-chloroethoxy)benzothiazole and 2-amino 4-(2-hydroxyethoxy)-benzothiazole were prepared by diazotization and coupling with different N,N-disubstituted anilines.
