Periodate photographic bleaching methods |
摘要 |
Color photographic elements are processed with an acidic periodate bleaching composition that may also include chloride ions as a rehalogenating agent. Bleaching is carried out after color development is stopped with an acidic stop bath. The processing method provides relatively rapid bleaching without physical defects such as blistering or vesiculation.
