Photothermographic element and process. |
摘要 |
<p>A method of making a photothermographic silver halide element comprises the combination of (I) adding an alkyl carboxylic acid containing 8 to 22 carbon atoms to a layer of the element comprising photosensitive silver halide and (II) after preparation of the layer comprising silver halide and before exposure of the element to light heating the element uniformly at a temperature and for a time sufficient to enable the photothermographic element to exhibit increased latent image stability upon imagewise exposure to light. The photothermographic element includes photosensitive silver halide and an oxidation-reduction image forming combination in a polymeric binder. A developed visible image is provided in such a photothermographic element after exposure to light by uniformly heating the exposed photothermographic element to moderately elevated temperatures.</p> |
