摘要： 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.
