HEAT DEVELOPABLE IMAGING MATERIALS AND PROCESS Abstract of the Disclosure A heat developable photographic materiel comprising in reactive association (a) photosensitive silver halide, (b) an image-forming combination comprising (i) a complex of silver with a nitrogen acid selected from the group consisting of imidazole, pyrazole, urazole, 1,2,4-triazole and 1H-tetrazole nitrogen acids or combinations thereof, with (ii) an organic reducing agent, and (c) a polymeric binder, provide developed images without the need for processing solutions or baths. An image can be developed in this heat developable material by merely heating the material to moderately elevated temperatures. Other addenda employed in heat developable materials can be employed with the heat developable photographic materials described. - 1 -
