| Abstract: | With 5-mercapto-(1, 3, 4) thiadiazol-2-yl-thio]-acetic acid adopted as the adsorption group and trifluoro-acetic acid 2-( 4-amino-phenyl )-hydrazide as the strengthen groups respectively, a novel colorless DAR (A ) coupler was synthesized from N,N'-bis-(2-chloro-5-n-dodecyloxy-carbonyl) phenylmalonamide. The intermediates and the target compound were characterized and confirmed by means of IR, MS,()~1HNMR. It contributed much to the increase of the photosensitivity of the color negative film and without changing the absorption spectrum of the main coupler developed. |
