Synthesis and dyeing properties of some new monoazo disperse dyes derived from 2-amino-4-(2′,4′-dichlorophenyl)-1,3 thiazole

Ten new monoazo disperse dyes (4a–j) have been synthesized by coupling of diazotized 2-amino-4-(2′,4′-dichlorophenyl)-1,3 thiazole (2) with various N-alkyl derivatives of substituted aniline (3a–j) and their dyeing performance on polyester fiber has been assessed. These dyes are characterized by ele...
