A series of new heterocyclic disperse dyes has been prepared by subsequent diazotization of 2-methyl-3-3'-aminophthalimido-4(3H)-quinazolinone and coupling with various mono- and di-N-substituted derivatives of aniline. All the disperse dyes were charac- terized by their percentage yield, melting point, UV-visible spectrum, elemental analysis, in- frared spectrum and dyeing performance on nylon 66 and polyester fibres. The percentage dye bath exhaustion on different fibres was found to be reasonably good and acceptable. The dyed fibres showed fair to fairly good to good fastness to light and very good to excellent fastness to washing, rubbing, perspiration and sublimation.
