Abstract
A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein the silver halide color photographic material contains an uncolored magenta coupler and at least one compound capable of reacting with and fixing formaldehyde vapor, and at least 30 mol % based on the total amount of the uncolored magenta coupler present in the silver halide color photographic material is an uncolored 5-pyrazolone 2-equivalent magenta coupler. The silver halide color photographic material has good latent image stability and a reduced layer thickness and thus improved sharpness. It is further possible thereby to avoid a decrease in color density and the formation of fog normally present when the silver halide color photographic material is brought into contact with formaldehyde vapor during storage prior to color development processing.
