| 摘要 |
A heat developable photographic material comprising, in reactive association, (a) photosensitive silver halide, with (b) an image-forming combination comprising (i) a silver imidazoline-2-thione wherein the imidazoline-2-thione portion is a 1-methyl, 1-ethyl or 1-phenyl-4-imidazoline-2-thione, with (ii) an organic, silver halide developing agent and (c) a binder, can provide developed and stabilized images without the need for processing solutions or baths. An image can be developed and stabilized in this material by merely heating the material to moderately elevated temperatures after imagewise exposure. Other addenda employed in heat developable photographic silver halide materials can be employed with the heat developable photographic materials described.
