Abstract: Nine monoazo disperse dyes, 3-arylazo-8-nitro-2,4-dioxo- and 2,4-bis(morpholino/piperidino)- pyrimido[1,2-a]benzimidazoles, and three monoazo disperse reactive dyes, 3-arylazo-2,4-dicbloro-8-nitropyrimido[1,2-a]benzimidazoles were prepared and their dyeing performance on polyester and polyamide was assessed. The dyeings on polyester had yellow shades with low pick-up, moderate light fastness and good sublimation fastness and the dyeings on polyamide had orange shades with low pick-up and moderate light fastness.
