Abstract
Color photographic elements are processed with a highly acidic periodate bleaching solution including a rehalogenating agent and a strong acid. Bleaching is carried out after color development without any intervening processing steps, such as an acidic prebath. The processing method provides rapid bleaching without physical defects such as blistering or vesiculation, and minimizes the formation of Dmin.
