Abstract
The 6-methyl-3, 4-diphenyl-7-(2-phenylhydrazono) pyrimido [1', 2':1, 5] pyrazolo [3,4- c ] pyridazin-8( 7H )-one and 3,4-diphenyl-7-(phenyldiazenyl)pyrimido[1',2':1,5]pyrazolo[3,4- c ]pyridazine-6,8-diamine derivatives were applied to polyester fiber as disperse dyes. They were found to exhibit varying in hue from orange-yellow to orange-red, their absorption spectral characteristics, fastness properties and colour assessment are also reported.
