ABSTRACT:
A simple and effective peroxide bleaching method includes the use of a bleaching solution including a peroxide bleaching agent and chloride ion in an amount of at least 0.35 mol/l. An organic phosphonic acid or tertiary aminocarboxylic acid can also be present for stability. The method is useful for bleaching high silver bromide color negative photographic films containing at least 80 mol % silver bromide and from 0.5 to 5 mol % silver iodide in at least one silver halide emulsion.
