    • A photosensitive material comprises a photosensitive silver halide, an organic silver salt, a reducing agent, a polymerizable polymer precursor, a photopolymerization initiator and a heat-diffusible coloring matter. As a preferred embodiment, the photosensitive material comprises a photosensitive layer containing the photosensitive silver halide, the organic silver salt and the reducing agent, a polymerizing layer containing the polymerizable polymer precursor and the photopolymerization initiator, and a coloring material layer containing the heat-diffusible coloring material. A image forming method employing the photosensitive material comprises the steps of a) subjecting the photosensitive material to imagewise exposure; b) heating the photosensitive material; c) subjecting to whole areas exposure at least the polymerizing layer; and d) heating at least the coloring material layer to transfer the heat-diffusible coloring matter to an image-receiving material, thus forming a color image.
    • 感光材料包括感光卤化银,有机银盐,还原剂,可聚合聚合物前体,光聚合引发剂和热扩散着色剂。 作为优选实施方案,感光材料包括含有感光卤化银,有机银盐和还原剂的感光层,含有可聚合聚合物前体和光聚合引发剂的聚合层,以及含有热扩散性的着色材料层 着色材料。 使用感光材料的成像方法包括以下步骤:a)使感光材料进行成像曝光; b)加热感光材料; c)使整个区域至少暴露于聚合层; 以及d)至少加热着色材料层以将热扩散着色剂转移到图像接收材料,从而形成彩色图像。
