    • 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.
    • 公开了一种扩散转印彩色照相材料,其至少具有感光卤化银,粘合剂,能够释放或形成扩散染料的非扩散染料供体化合物,其对应于或者与将卤化银还原为 银和非扩散性过滤染料,其中过滤染料与染料供体化合物一起呈乳化分散体的形式。 加工材料的颜色分离性良好,形成图像的辨别性也良好。 储存后材料的原料膜不会降低过滤效果。 还公开了一种可热显影的彩色照相材料,其具有至少两层感光层B,该感光层B具有对于720至780nm的光的颜色敏感度的峰值,以及具有色彩敏感度峰值的感光层A 在790〜860nm的光下,在感光层B的最大灵敏度与感光层A的最大灵敏度相同或更低的支持体上。该材料具有优异的时间依赖性 生胶片储存稳定。 可以开发出很少的温度依赖性和水量依赖性,以提供高锐度的图像。
