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.

Silver halide color photographic materials containing

A color photographic material having at least one silver halide emulsion layer containing a 3-anilino-5-pyrazolone type magenta dye forming coupler and a phenolic compound for improving the light fastness of the magenta dye formed by the coupling reaction of the magenta dye forming coupler with the oxidation product of a color developing agent in combination with a nucleus-substituted hydroquinone, in which the reduction of the coupling reactivity of the magenta dye forming coupler during the storage of the color photographic material caused by the presence of the phenolic compound is prevented efficiently.
