    • A process for preparing a photothermographic material with increased photosensitivity, the photothermographic material comprising a support and a photo-addressable thermally developable element, exclusive of a compound R-S(M) n wherein R is an aliphatic hydrocarbon, aryl or heterocyclic group, M is a hydrogen atom, or cation, and letter n is a number determined so as to render the molecule neutral and also exclusive of a compound capable of releasing a mobile dye corresponding to or inversely corresponding to the reduction of silver halide to silver at elevated temperatures, the photo-addressable thermally developable element containing a photosensitive agent in catalytic association with a light-insensitive organic silver salt, a reducing agent for the light-insensitive organic silver salt in thermal working relationship therewith and a binder, comprising the steps of: (i) increasing the photosensitivity of a photosensitive silver halide by chemical sensitisation with a chemical sensitising merocyanine dye containing a thione group in a non-oxidative aqueous medium, optionally in the presence of the light-insensitive organic silver salt, thereby producing the photosensitive agent; (ii) coating the support with one or more aqueous solutions or dispersions together containing the light-insensitive organic silver salt, the photosensitive agent, the reducing agent and the binder; (iii) drying the coating or coatings thereby producing the photo-addressable thermally developable element.
    • 一种制备具有增加的光敏性的光热敏成像材料的方法,所述光热成像材料包含载体和光寻址热可显影元素,不包括化合物RS(M)n,其中R是脂族烃,芳基或杂环基,M是 氢原子或阳离子,并且字母n是为了使分子中性而且除了可以释放与升高的温度下的卤化银还原成银相反或相反地对应的可移动染料的化合物的数量, 包含与光不敏感有机银盐催化缔合的感光剂的光寻址热可显影元件,与其热处理关系的光不敏感有机银盐的还原剂和粘合剂,包括以下步骤:(i) 通过化学敏化增加光敏卤化银的感光度 任选在光不敏感的有机银盐存在下,在非氧化性水性介质中含有硫酮基团的部分花菁染料,从而制备感光剂; (ii)用一种或多种含有光不敏感有机银盐,感光剂,还原剂和粘合剂的水溶液或分散体涂覆载体; (iii)干燥涂层或涂层,从而产生可光寻址的热显影元件。
