ABSTRACT:

Hot-brand reactive dyes have been prepared by coupling diazotised 4,4'-methylene-bis-o-bromo aniline, with various anilino cyanurated coupling components such as H-acid, Chicago acid, N-methyl-J-acid, T-acid, sulphotobias acid, Bronner acid, Gamma acid, Tobias acid, Cleve acid and J-acid and their dyeing performance as reactive dyes has been assessed on Silk, Wool and Cotton fibres.
