    摘要： A dye diffusion transfer type heat developable color light-sensitive material is described including a support having thereon at least three light-sensitive layers containing, in combination, silver halide emulsions which are sensitive in different spectral regions from one another and dye providing compounds capable of releasing or forming diffusible dyes having different hues from one another, wherein the material has an exposure side which is subjected to incident light from a light source, wherein at least two layers of the at least three light-sensitive layers include a first light-sensitive layer containing an emulsion spectrally sensitized to a part of infrared rays and a second light-sensitive layer which is positioned on the exposure side nearer to the light source than is the first light-sensitive layer and contains an emulsion spectrally sensitized to a part of infrared rays having a wavelength shorter than that of the infrared rays applied to the emulsion of the first light-sensitive layer, and the first light-sensitive layer contains a non-transferring filter dye which absorbs at least a part of light to which the second light-sensitive layer is exposed, and wherein the light-sensitive layer or layers other than the first and second light-sensitive layers can be arranged in any order.
