Abstract
Vinylsulphone disperse reactive dyes were synthesized by diazotizing 2-methoxy-5-methyl-4- (sulfatoethylsulfonyl) aniline and coupling with substituted pyridone derivatives. The synthesized dyes were applied successfully on polyester without dispersing agent and the dyeing showed good leveling and build up with desired colour yield. The dyeing was dependent on the pH and the optimum pH was found to be 5, similar to that employed in conventional polyester dyeing. The fastness properties obtained are excellent and comparable with the conventional disperse dyes
