Abstract
Photographic elements are described which comprise a support having thereon at least one image dye-providing layer unit and at least one layer containing an immobile anionic organic acid having an equivalent weight based on acid groups of at least 70 and less than 800. In one embodiment, photographic elements of this invention can be contacted with a transition metal-ion complex such as a cobalt(III) ion complex before contact with a fixing bath and sufficient transition metal ion will be retained in the photographic element to bleach the silver in said element.
