摘要:
Disclosed is a diffusion transfer color photographic material at least having a light-sensitive silver halide, a binder, a non-diffusive dye donor compound capable of releasing or forming a diffusive dye in correspondence or reverse correspondence with the reaction of reducing the silver halide to silver, and a non-diffusive filter dye, on a support, in which the filter dye is in the form of an emulsified dispersion along with the dye donor compound. The color separatability of the processed material is good and the discrimination of the formed image is also good. The raw film of the material is free from lowering of the filter effect after storage. Also disclosed is a heat-developable color photographic material having at least two layers of a light-sensitive layer B having a peak of color sensitivity to a light of from 720 to 780 nm and a light-sensitive layer A having a peak of color sensitivity to a light of from 790 to 860 nm, on a support, in which the maximum sensitivity of the light-sensitive layer B is same as or lower than the maximum sensitivity of the light-sensitive layer A. The material has excellent time-dependent raw film storage stability. It may be developed with little temperature dependence and water amount dependence to give an image of high sharpness.
