Some hot brand reactive dyes have been synthesized by coupling of tetrazotized 4,4’-methylene bis(2-nitro aniline) and coupled with two moles of various 2-((4-amino-3-methoxyphenyl) sulphonyl)ethyl hydrogen sulphato cyanurated coupling components such as H-acid, Gamma acid, S-acid, Peri acid, J-acid, N-Methyl J-acid, N-Phenyl J-acid, N-Benzoyl J-acid, K-acid, Koch acid, Bronner acid, Laurent acid, Cleve acid and Tobias acid. They were characterized by nitrogen elemental analysis, IR and 1HNMR 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.
