    • In a heat-developable color light-sensitive material comprising a support having thereon at least two light-sensitive layers each comprising a light-sensitive silver halide, organic silver salt, dye-donating material capable of releasing or forming a diffusible dye by heat development, reducing agent, and hydrophilic binder, said at least two light-sensitive layers differing from each other in the color sensitivity of said light-sensitive silver halide and in the hue of said diffusible dye, said heat-developable color light-sensitive material, wherein at least one of said light-sensitive layer(s) containing said dye-donating materials are hardened with a hardening agent for said hydrophilic binder. The foregoing heat-developable color light-sensitive material prevents diffusion of the dye-donating material and reduces or prevents the color-crossover phenomenon. Transferability of the dye is also improved as is scratch resistance of the photographic component layers.
    • 在一种可热显影的彩色感光材料中,包括其上具有至少两个感光层的支撑体,每个感光层包含感光卤化银,有机银盐,能够通过热显影释放或形成可扩散染料的染料供体材料 ,还原剂和亲水性粘合剂,所述至少两个感光层在所述感光卤化银的颜色敏感性和所述可扩散染料的色调中彼此不同,所述热显影色光敏材料, 其中含有所述染料供给材料的所述感光层中的至少一个用所述亲水性粘合剂的硬化剂硬化。 上述可热显色的感光材料防止染料供体材料的扩散,并减少或防止颜色交叉现象。 染色剂的转印性也得到改善,因为照相组分层的耐擦伤性。
