Abstract

Abstract A color photographic material having differently sensitized silver halide emulsion layers including a silver halide emulsion layer containing a 3-anilino-5-pyrazolone magenta dye-forming coupler, the coupler having a halogen atom or an alkoxyl group at the 2-position of the anilino group and an aliphatic acylamino group at the 5-position of the anilino group.
