Abstract
Abstract A method for processing a silver halide color photographic material for prints comprising a color developing step, a bleach-fixing step, and either a stabilizing step or a water washing step is described, wherein the silver halide color photographic material comprises a reflective support having thereon at least one silver halide emulsion layer containing a silver halide having a silver chloride content of not less than 90 mol % and substantially not containing silver iodide, and the color developing step is conducted using a processing solution that does not substantially contain benzyl alcohol. According to the method of the present invention, the amount of water required in a water washing step or a stabilizing step can be greatly reduced without decreasing liquid stability of the water for washing or the stabilizing solution, and color prints having improved preservability are obtained. The method is particularly useful when the silver halide color photographic material contains a pyrazoloazole type magenta coupler.
