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.

Key words: DAR coupler, adsorption group, strengthen group, synthesis, application
