Abstract: Thirteen 4-methoxy-2[H/substituted-4'-(N',N-disubstituted amino)phenylazo]benzothiazoles(Va-m) were prepared by coupling diazotized 2-amino-4-methoxybenzothiazole (II) with various substituted aniline derivatives (lVa-m) and their dyeing performance on polyester fibres was assessed. All the compounds (Va-m) showed good substantivity for polyester fibres and gave bright dyeing with moderate to good light fastness and good to excellent fastness to washing, perspiration, rubbing and sublimation.
