ABSTRACT:
Color photographic elements are bleached after exposure and development by using a peroxide bleaching solution. This solution comprises a peroxide bleaching agent, chloride ions in an amount of at least 0.35 mol/l, a first acid which is an organic phosphonic acid and a second acid which is a polyaminocarboxylic acid having one or more secondary amines at a pH of 8 to 11. The bleaching solution is stabilized by the presence of the two acids.
