摘要：
A diffusion transfer silver halide photographic material containing a color developing agent represented by the following formula (I) in a hydrophilic colloid layer provided on a support: ##STR1## wherein C.sub..alpha. represents a carbon atom; Z represents a carbamoyl group, an acyl group, an alkoxycarbonyl group, or an aryloxycarbonyl group; and Q represents an atomic group for forming a unsaturated ring together with C.sub..alpha., whereby a color diffusion transfer silver halide photographic material containing a novel color developing agent from which a diffusible dye can be formed is provided.
