摘要： A color photographic silver halide material is processed effectively without formation of rust after the bleaching step. Bleaching is accomplished using an iron chelate of a biodegradable aminopolycarboxylic acid chelating ligand that has a tendency to form "rust" or ferrous hydroxide in processing baths conventionally used after bleaching, such as washing solution. This tendency to form rust is overcome by spraying the bleached film with a washing solution before fixing, and without immersion of the film in that washing solution.
