A series of bisazo reactive dyes has been synthesized by coupling of tetrazotized 4,4’-methylene bis anthranilic acid with various 2-((4-amino-3-methoxy phenyl) sulphonyl)ethyl hydrogen sulphato cyanurated coupling components such as H-acid, Gamma acid, J-acid, N-Methyl J-acid, N-Phenyl J-acid, Chicago acid, S-acid, K-acid, Bronner acid, Peri acid, Laurent acid, Koch acid, Naphthionic acid and Tobias acid. They were characterized by nitrogen elemental analysis, IR and 1 HNMR spectra. The dyeing performance of all these dyes on wool, silk and cotton fibres gave fair to good light fastness, good to excellent wash fastness and rubbing fastness. Spectral properties and colorimetric data (L* , a* , b* , c* , H* and K/S) have also been investigated.
