PURPOSE:To render solubility in organic solvents sufficient and to enable high yield synthesis, by using a specified 3-anilino-5-pyrazolone coupler. CONSTITUTION:To a color photographic material is added a photographic magenta coupler represented by the general formula (in which R1 is H, OH, or 4 to 18 C alkyl; R2 is such C alkyl; R3 is H, halogen, lower alkyl, or lower alkoxy; X, Y, and Z are each H, halogen, lower alkyl, lower alkoxy, cyano, alkylacylamino, alkylsulfamoyl, alkylcarbamoyl, alkoxycarbonyl, or alkylsulfonyl; and W is H or a group easily releasable by oxydation coupling). |
