| titleOfInvention | Heat erasable photographic element comprising silver halide, a cobalt (iii) amine salt and a weak complexing agent for oxidized silver |
| abstract | Abstract of the Disclosure A heat erasable photographic material comprises, in reactive association, in a suitable binder: (a) photographic silver halide; (b) a mild oxidizing agent which consists essentially of a cobalt(III) amine salt which, upon heating of the photographic material, will oxidize any latent image silver present in the photographic material; and (c) a weak complexing agent for the oxidized silver. Any latent image silver in the photographic material is erased upon brief uniform healing of the photographic material. The photographic material is light handleable prior to uniform heating. After uniform heating, the photographic material is capable of being imagewise exposed and processed to produce a developed silver image. The photographic material may comprise a selected silver halide developing agent. A developed image is produced in a heat erasable photographic material by (1) first uniformly heating the material at a temperature and for a time sufficient to erase any latent image silver in the photographic material, then (2) exposing the material to light to produce a developable image and (3) thereafter developing an image. The photographic material is preferably a photothermographic material. |
