Abstract
Novel monoazo disperse dyes based on various 2-aminoheterocycles were prepared using N-methyl-N-(2-hydroxyethyl)aniline as the coupling component. All the dyes were applied as disperse dyes on nylon fabric. These dyes have been found to give a wide range of colour shades with very good depth, brightness and levelness on nylon fabric. The visible absorption spectra, elemental analysis and Rf values were investigated. The percentage dye bath exhaustion on fabric was found to be very good. The dyed fabric showed very good to excellent fastness to light, washing, rubbing and perspiration. The sublimation fastness was found to be excellent.
