ABSTRACT:
A method for desilvering an imagewise exposed and color development processed silver halide color light-sensitive material comprising processing the imagewise exposed and color developed silver halide color light-sensitive material with a processing solution exhibiting bleaching ability which contains at least one of hydrogen peroxide and a compound capable of releasing hydrogen peroxide, wherein the silver halide color light-sensitive material has an emulsion layer comprising a light-sensitive silver halide with at least 90 mol % silver chloride and substantially no silver iodide, the processing solution exhibiting a bleaching ability contains at least one water-soluble chloride, the color developed silver halide color light-sensitive material contains 1 mmol/m.sup.2 or less of a color developing agent in the light-sensitive material when introduced into the processing solution exhibiting a bleaching ability and the desilvering is completed within 30 seconds. The desilvering proceeds rapidly in a stable manner without causing environmental pollution.
