摘要： A post-activation type dry image forming material comprising (I) a silver salt component reducible to free silver upon light exposure and including silver iodide; (II) a redox reactive composition capable of making a visual change by a redox reaction of said composition, said reaction being initiated by heating in the presence of free silver; (III) an oxidizing agent for free silver which has an oxidizing capacity for free silver but is rendered photosensitive by heating and which, upon light exposure after said heating, is suppressed with respect to the oxidizing capacity for free silver and capable of catalytically promoting the redox reaction of said composition; and (IV) a photoreactive oxidizing agent, upon light exposure, capable of returning the reduced oxidizing agent for free silver to the original state. A post-activation type dry image forming material which is extremely excellent in stability of the raw image forming material, that is, can be stored in a light room for a time as long as a period of the order of years and which has high sensitivity can, for the first time, be realized by the ingenious combination of components. The effect of the interaction between the components, especially between the components (I), (III) and (IV) is noticeable in imparting to the present image forming material an extremely high stability of the raw image forming material.

摘要： A novel dry image forming material comprising in one or more layers on a support (a) a non-photosensitive organic silver salt oxidizing agent, (b) a reducing agent for silver ions, (c) a silver halide component or a silver halide-forming component, (d) a toning agent and (e) a lipophilic binder, characterized by the inclusion of a specific 2-(2'-hydroxyphenyl)benzotriazole compound having bulky tert-butyl or tert-amyl groups at its ortho- and para-positions relative to the hydroxyl group in a layer containing the component (a). The dry image forming material of the present invention has high storage stability prior to use for image formation. When the dry image forming material comprises a combination of a silver salt oxidizing agent-containing layer comprising the specific 2-(2'-hydroxyphenyl)benzotriazole compound and a reducing agent-containing layer comprising a high impact acrylic resin as a binder material, the material is remarkably improved in storage stability of raw material in the dark or under light with wavelengths of 450 nm or more and the stability of a latent image, and shows minimized variation in image quality with heat development conditions. When the dry image forming material comprises, as the component (a), a silver salt of long chain fatty acid having 16 or more carbon atoms and, as the component (c), a silver halide component including silver iodide or a silver halide-forming component capable of forming a silver halide component including silver iodide, and further comprises (g) an oxidizing agent for free silver, (h) a photoreactive halogeno oxidizing agent and, in the layer containing the components (a), (c), (e) and (f), (i) a specific cyanine spectral sensitizing dye, the material is of the post-activation type and spectrally sensitized without sacrificing the storage stability of raw material.
