-
Three DAR cyan couplers(6) were synthesized based on 1-hydroxyl-N-{4-(2,4-di-tert-phenylphenoxyl)-butyl}-2-naphthamide. Linking group is 2,5-dimercapto-1,3,4-thiociazole, and 1-formyl-2-(4-aminophenyl)hydrazine, 1-acetyl-2-(4-aminophenyl)hydrazine and 1-trifluoacyl-2-(4-aminophenyl)hydrazine are the accelerator. The structures of the couplers are identified by IR, 1H NMR, MS and elemental analysis.
