ABSTRACT:
Aminosuccinic acid chelants are disclosed which have been found to be applicable in photographic processes. The aminosuccinic acids can be used in a method of bleaching or bleach-fixing a silver halide photographic material comprising contacting the photographic material with a bleaching solution containing at least one metal complex of a polyamino disuccinic acid and one or more metal complexes of a polyamino monosuccinic acid or a monoamino monosuccinic acid.
