摘要：
A series of disperse dyes have been synthesized by diazotation of 2-aminothiophene derivative and coupling with various, N-arylmaleimides. The dyes were characterized by IR spectral studies, visible absorption spectra and elemental analysis. The dyeing performance of these dyes was assessed on nylon fabric. These dyes were found to give yellowish brown to reddish violet shades on dyeing with very good depth, levelness, and brightness on fabric. The percentage dyebath exhaustion and fixation on fabric was found to be very good. The dyed fabric showed poor light fastness and good to excellent fastness to washing, rubbing, perspiration, and sublimation.
