ABSTRACT:
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.
