Abstract
A color image-forming process is disclosed, which comprises imagewise exposing a silver halide color photographic material comprising a support having thereon at least one light-sensitive layer containing at least one coupler capable of forming a dye upon a reaction with an oxidation product of an aromatic primary amine color developing agent and a silver halide emulsion spectrally sensitized with a dye represented by the following general formula (I), (II) or (III), substantially excluding silver iodide, and containing about 80 mol % or more silver chloride, processing the exposed photographic material with a color developer, then processing it with a solution having a pH of not more than about 6.5 and having a bleaching ability within about 75 seconds: ##STR1## wherein the symbols have the meanings described hereinafter. A silver halide color photographic material to be processed in accordance with the method described above is also disclosed.
