ABSTRACT:
A color photographic light-sensitive material is described, comprising a support having thereon a silver halide emulsion layer containing at least one coupler represented by formula (I) ##STR1## wherein R.sub.1 represents an anilino group, an acylamino group or a ureido group, R.sub.2 represents an aralkyl group, an alkyl group, or an alkenyl group, X.sub.1, X.sub.2, and X.sub.3 each represents hydrogen, an alkyl group, a halogen atom, an alkoxy group, an aryloxy group, an acylamino group, a carbamoyl group, a sulfamoyl group, a sulfonyl group or a cyano group and X.sub.1, X.sub.2, and X.sub.3 may be the same or different, and at least one of said silver halide emulsion layer and a hydrophilic colloid layer adjacent thereto containing a 1-phenyl-3-pyrazolidone compound having a diffusion resistant group in the presence of an organic solvent having a high boiling point for a photographic additive.
The photographic light-sensitive material provides a magenta color image having a high sensitivity.
More preferably, said color photographic light-sensitive material further contains a hydroquinone compound in at least one of said silver halide emulsion layer and said hydrophilic colloid layer adjacent thereto.
The photographic light-sensitive material provides a magenta color image having a high sensitivity without forming undesired fog using relatively low amounts of silver.
