Definitions
- the present invention relates to an image-recording material, in particular, to a photothermographic or thermographic material excellent in silver tone.
- a photothermographic or thermographic material has been proposed for long and described, for example, in U.S. Patents 3,152,904 and 3,457,075, D. Kleinboer, Thermally Processed Silver System , "Imaging Processes and Materials", compiled by Sturge, V. Walworth, A. Shepp, 8th Ed., Neblette, p. 279 (1989).
- a photothermographic material generally has a photosensitive layer comprising a catalytically active amount of photocatalyst (e.g., silver halide), a reducing agent, a reducible silver salt (e.g., organic silver salt), and a toning agent which controls the tone of silver according to necessity dispersed in a binder matrix.
- a photothermographic material forms a silver image of black color by heating at high temperature (e.g., 80°C or more) after image exposure to cause an oxidation reduction reaction between silver halide or a reducible silver salt (functioning as an oxidizing agent) with a reducing agent.
- the oxidation reduction reaction is accelerated by the catalytic action of the latent image of the silver halide generated by exposure. Therefore, the silver image of black color is formed in the exposure region.
- a photothermographic material is generally stored as a bulk product after coating until processed and shipped.
- the storage stability of a coated bulk product during that time is not good and the improvement of the storage stability is desired. Further, it is desired that the tint of a silver image is not varied by the photothermographic temperature.
- An object of the present invention is to improve the storage stability of a coated bulk product and silver tone in a (photo)thermographic material, in particular, a photothermographic material.
