Abstract: Abstract Six novel fluorescent disperse dyes were synthesized by diazo-coupling reaction. As dye intermediates, two diazo components having 5-amino-4-arylazo-3-methyl-1H-pyrazoles moieties were initially prepared, diazotized and coupled with three pyrrolinone esters (PES) derivatives to give azo-hydrazone… read more here.
