摘要

A series of new heterocyclic monoazo disperse dyes have been prepared by coupling diazotized 1H-pyrazolo [3,4-b]quinoline-3-amine with various mono and di-N-substituted derivatives of aniline. All the disperse dyes were characterized by their percentage yield, melting point, UV-visible spectroscopy, elemental analysis, infrared spectrdscopy and dyeing performance on Nylon-66 and polyester fibres. The percentage dyebath exhaustion of different fibres have found to be reasonably good and acceptable. The dyed fibres show fairly good to good fastness to light and very good to excellent fastness to washing, rubbing, perspiration and sublimation.
