ABSTRACT:
A silver halide color photosensitive material is disclosed. The photosensitive material comprises a support and a hydrophilic colloidal layer containing a yellow coupler. According to the present invention, the layer further contains a color image stabilizer in an amount of 10 to 200 mole % based on the amount of the yellow coupler. The color image stabilizer and the yellow coupler are together contained in droplets of a medium which are dispersed in the layer. The color image stabilizer is an organic compound having the following formula [I] or [II]: ##STR1## in which each of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently is hydrogen, an alkyl group, an alkenyl group, an aryl group, a heterocyclic group, an alkoxycarbonyl group, an aryloxycarbonyl group, an acyl group, a sulfonyl group, a sulfinyl group, a phosphoryl group, a carbamoyl group or a sulfamoyl group; each of R.sup.5 and R.sup.6 independently is hydrogen, an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, an aryl group, a heterocyclic group, an acyl group, a sulfonyl group, a phosphoryl group, a sulfinyl group, an alkylcarbamoyl group, an arylcarbamoyl group, an alkylsulfamoyl group, an arylsulfamoyl group, an alkoxycarbonyl group or an aryloxycarbonyl group; and Y is a non-metallic atomic group which forms, together with the two nitrogen atoms, a 5- to 8-membered heterocyclic ring.
