A series of new heterocyclic mono azo reactive dyes 7a-m were prepared by diazotization of 2-phenyl-3-{4'-[N-(4"-aminophenyl)carbamoyl]-phenyl}- quinazoline-4(3H)-one-6-sulphonic acid (3) and coupling with various cyanurated coupling components 6a-m and their dyeing performance on silk, wool and cotton fibres was assessed. These dyes were found to give a variety of colour shades with very good depth and levelness on the fibres. All the compounds were identified by conventional method (IR and 1H-NMR) and elemental analyses. The percentage dye bath exhaustion on different fibres was reasonably good and acceptable. The dyed fibre showed moderate to very good fastness to light, washing and rubbing.
