摘要： Heat bleachable elements have antihalation layers composed of metallized or unmetallized formazan dyes, hexaarylbiimidzoles having alkoxy substituents and film forming binders that soften upon heating. These layers are rapidly bleached at relatively low temperatures. Polymeric acidic layers adjacent the antihalation layers provide an acidic component that increases bleaching rates when the acidic layer is also softened during processing.
