Abstract
Abstract In a method of processing a lightsensitive silver halide color photographic material comprising subjecting a lightsensitive silver halide color photographic material comprising a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer provided on a base, the blue-sensitive silver halide emulsion layer containing a high speed reactive yellow coupler having a relative coupling reaction rate of not less than 0.3, to color development, followed by processing with a processing solution having a fixing ability and then processing with a stabilizing solution without involving any substantial washing step, the improvement wherein the stabilizing solution contains a sulfite with at least 1×10 -3 mole per 1 liter of the stabilizing solution. According to the processing method, a dye image having a superior stability with a lapse of time can be obtained.
