Synthesis and application of vinylsulphone disperse reactive dyes derived from pyridone derivatives on polyester fabric
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 wa...
