摘要： In a photothermographic element comprising (A) at least one photosensitive layer comprising a photosensitive component, such as photosensitive silver halide or a diazotype photosensitive material, (B) at least one layer comprising a processing agent for the photosensitive component and (C) a separation polymer between (A) and (B), increased preexposure storage stability is provided by a polysulfonamide as separation polymer (C). After imagewise exposure of the photothermographic element, an image can be developed by merely heating the element to moderately elevated temperatures.

摘要： A heat developable photographic material 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.
