Abstract
Active methylene compound such as ethyl acetoacetate was coupled with diazotized arylamines to give ethyl arylazoacetoacetates. When the obtained compounds refluxed with 3-hydrazinyl-4,5-diphenyl-1 H -pyrazolo[3,4- c ]pyridazine in the presence of ethanol yielded 1-(4, 5-Diphenyl-1 H -pyrazolo[3, 4- c ]pyridazin-3-yl)-3-methyl-4-(2-phenylhydrazono)-1 H -pyrazol-5(4 H )-one derivatives. The dyes were applied to polyester fabric, and their absorption spectral characteristics, fastness properties and color assessment measured.
