A color photographic material comprising a support having coated thereon at least one silver halide emulsion layer containing a magenta dye forming coupler having a 3-anilino-5-pyrazolone ring in which the ortho position of the anilino group at the 3-position is substituted with a halogen atom, an alkyl group, an alkoxy group, an amide group, an aryl group, an aryloxy group, a cyano group, a nitro group, a hydroxyl group, or an amino group and having a hydrophobic residue of 8 to 32 carbon atoms, the silver halide emulsion layer or an emulsion layer adjacent to the silver halide emulsion layer containing a hydroquinone derivative having at least one substituent of at least 8 carbon atoms or a precursor capable of providing such a hydroquinone derivative by hydrolysis. The color photographic material provides magenta dye images having good color separation and less color fog and less color stains in the highlight areas.
