Abstract

To achieve superior desilvering property and reduced stains even with the use of a biodegradable bleaching agent in a dilute concentration, the processing is conducted with a processing solution comprising a ferric complex salt of the compound of formula (I) or (II) and, for example, a 2-carboxypyridyl and having bleaching ability. (In the formulae, R.sub.1 to R.sub.5 represent, for example, a hydrogen atom or a carboxyl group, L.sub.1 to L.sub.5 represent, for example, an alkylene group, G.sub.1 and G.sub.2 represent, for example, a carboxyl group or an aryl group and X represents, for example, a hydrogen atom). ##STR1##
