Аннотация

А series of novel monoazo disperse dyes derived from the coupling of diazotized 2-aminobenzo[b]thiophenе derivatives with N-arylmaleimides is described. The monoazo disperse dyes applied to nylon fabric and their dyeing performance has been assessed. These dyes have been found to give light yellow to reddish pink colour shades with very good depth and levelness on nylon fabric. The dyed fabric show moderate light fastness and excellent washing, rubbing, perspiration and sublimation fastness. The percentage dyebath exhaustion on nylon fabric has been found to be good and acceptable.
