Abstract


Acetylacetone was coupled with diazotized aryl amines to give  arylazoacetylacetones; these when refluxed with 5-amino-3,4-diphenylthieno[2,3-c]pyridazine-6-carbohydrazide in glacial acetic acid yielded the corresponding 5-amino-6-[[4-arylazo-3,5-dimethylpyrazol-1-yl]-carbonyl]-3,4-diphenylthieno[2,3-c]pyridazine dyes. The dyes were applied to polyester fabric, and their spectral and fastness properties measured.
