Abstract
A heat developable, photographic material comprising, in reactive association, (a) a photosensitive, transition metal carbonyl compound, (b) an oxidation-reduction image-forming combination comprising (i) a tellurium (II) or (IV) compound as an oxidizing agent, with (ii) a reducing agent, and (c) a binder can provide an improved non-silver image. After imagewise exposure of the heat developable material, an image can be developed by merely heating the material.
