Studying the Synthesis and Dyeing Performance of New Polyfunctional Reactive Azo Dyes Based on O-Dianisidine

A series of polyfunctional reactive azo dyes were synthesised; where vinylsulfone was diazotised and coupled with chicago acid, which on condensation with bis cyanurated o-dianisidine producing dyes. These poly functional reactive azo dyes produce orange to pink shades on cotton and wool. All the compounds were characterised by elemental analysis and spectral data.
