Abstract: Twenty-two azo disperse dyes (Vla-k and VIIa-k) were prepared by coupling diazotized 1-(4aminophenyl)- 2-phenyl-4-(substituted Benzylidene)-5-imidazolones (III and IV) with various naphthol derivatives (Va-k) and their dyeing perfol1i1anceon nylon and polyester fibres has been assessed. All the imidazolone dyes showed fair to good fastness to light and very good to excellent fastness to washing, rubbing, perspiration and sublimation.
