ABSTRACT:
There is disclosed a method for processing a silver halide color photographic light-sensitive material, which comprises processing a silver halide color photographic light-sensitive material that contains a color-forming reducing agent, with an alkaline solution that is substantially free from any color-developing agent, and then processing the light-sensitive material with a bleach-fix solution that contains a ferric complex salt of a compound represented by formula (I) or (II): ##STR1## wherein, in formula (I), R.sub.1 represents a hydrogen atom, or an aliphatic hydrocarbon, aryl, or heterocyclic group; L.sub.1 and L.sub.2 each represent an alkylene group; and M.sub.1 and M.sub.2 each represent a hydrogen atom or a cation; and wherein, in formula (II), R.sub.21, R.sub.22, R.sub.23, and R.sub.24 each represent a hydrogen atom, or an aliphatic hydrocarbon, aryl, heterocyclic, hydroxyl, or carboxyl group; t and u are each 0 or 1; W represents a divalent carbon-containing linking group; and M.sub.21, M.sub.22, M.sub.23, and M.sub.24 each represent a hydrogen atom or a cation. According to the processing method, by the use of a material excellent in environmental preservation, the light-sensitive material after the processing in a processing step that was excellent in handleability was less in stain, and also the processing method is excellent in image stability in the processed light-sensitive material.
