PYRIDAZINE AND ITS RELATED COMPOUNDS: PART 30.1 SYNTHESIS AND APPLICATION OF SOME MONOAZO DISPERSE DYES DERIVED FROM PYRIDAZIN-3(2H)-ONE

摘要

Normal 0 A series of monoazo disperse dyes based on 5,6-diphenyl-2,3-dihydro-3-oxopyridazine-4-carbohydrazide was prepared by reacting with azobenzeneacetylacetone, ethyl azobenzeneacetoacetate, and azobenzenemalononitrile derivatives. The dyeing performance of these dyes was assessed on polyester fabric. The dyes were found to give yellow to brown color shades on dyeing with good depth levelness on fabric. The dye bath exhaustion, fixation and fastness properties of the dye were also determined.
