Abstract:
Color photographic silver halide materials, especially color photographic papers, are processed effectively with reduced iron retention after bleaching with a biodegradable bleaching composition. Bleaching is accomplished using an iron chelate of a biodegradable chelating ligand in the presence of a polyphosphonic acid. This bleaching step is followed by fixing using a fixing composition that includes a fixing agent and a polycarboxylic acid.
