摘要： A method for processing a silver halide color photographic material is provided, which comprises subjecting an imagewise exposed silver halide color photographic material having at least one silver halide emulsion layer on a reflective support to color development for a period not exceeding 2 minutes and 30 seconds using a color-developing solution containing substantially no benzyl alcohol, a sulfite in a concentration of 8.times.10.sup.-3 mol/liter or less, and a hydroxylamine in a concentration of 1.5.times.10.sup.-2 mol/liter or less, thereby achieving high color densities of the developed images and reduced fog. The effects of this method are particularly significant in photographic paper containing a pyrazoloazole type magenta coupler.

摘要： A method for processing a silver halide color photographic light-sensitive material comprises the steps of developing the light-sensitive material with a color developer containing an aromatic primary amine color developing agent, desilvering, washing with water and/or stabilizing the material in which at least one processing solution used in at least one step of the processing contains at least one compound selected from the group consisting of sulfinic acids and salts and precursors thereof. This method makes it possible to effectively prevent the formation of stains due to not only the components of the light-sensitive material per se but also those attributable to the processing solutions, during processing or storage with time, and to enhance the stability of processing solutions.
