ABSTRACT:
A heat developable, photographic material comprising (a) a photographic metal compound with (b) an oxidation-reduction image-forming combination comprising (i) a tellurium (II) or (IV) compound as an oxidizing agent and (ii) a reducing agent provides an improved amplified image. The photographic metal compound can be, for example, photograhic silver halide. A developed image can be provided in the material after imagewise exposure by heating the element to moderately elevated temperatures.
