چکیده    A range of azo disperse dyes was prepared by coupling diazotized 2-amino-4-(p-nitrophenyl)-5-nitrothiazole with various substituted arylamines. spectral properties in the infrared and visible range of the dyes obtained were investigated. all the dyes, when applied on cellulose triacetate fabric as 2% shade, showed fairly good to very good light fastness and very good to excellent fastness to washing, perspiration, rubbing and sublimation. all the dyes gave a wide range of reddish brown to indigo shades with very good depth and levelness on fabric. the purity of dyes was checked by thin layer chromatography. the percentage dyebath exhaustion and fixation on fabric was reasonably good and acceptable.
