Abstract:
Various monoazo reactive dyes have been synthesized by coupling diazotized 2-amino-5-(3-carboxy- 4-(4-oxo-2-phenylquinazolin-3(4H)-yl) benzyl) benzoic acid with various 2-(4-aminophenylsulphonyl) ethyl hydrogen sulphato cyanurated coupling components such as H-acid, gamma acid, J-acid, NMethyl J-acid, N-Phenyl J-acid, S-acid, Naphthionic acid, Peri acid, Bronner acid, Tobias acid, K-acid and Koch acid. They are characterised by elemental analysis, IR and PMR spectra. Their dyeing performance has been assessed on cotton, wool, and silk fibres.
