Abstract
Abstract A quick desilvering process of silver halide color photographic materials is provided, wherein the total amount of coated silver is 5.2 g/m 2 or less, an average iodide content in the whole light-sensitive silver halide grains is 5.5 mol% or less; and a 2-equivalent magenta polymer coupler is included as a magenta coupler, and bleach-fixing treatment, or bleaching treatment at a pH of 5.5 or less, or desilvering treatment in the presence of a specific desilvering accelerator is carried out. Silver halide color photographic materials which permit the quick desilvering are also provided. These contain a specific desilvering accelerator.
