Hot brand reactive dyes have been synthesized by coupling tetraotised 4,4’-methylene bis-2,5-dimethy1 aniline with various m-toluidino cyanurated coupling components and their dyeing performance has been accessed on silk, wool and cotton fibres. The purity of the dyes was checked by thin layer chromatography (TLC). For the structure confirmation of all the dyes were characterized by IR spectroscopy. A representative NMR analysis of one of all the synthesized dyes was performed. All the spectroscopy results were consistent with the structure of dyes.
