Abstract: Photographic sensitive materials for a color-diffusion transfer process which are particularly useful in a wide variety of temperature and climate conditions are disclosed. The materials are comprised of a red-sensitive emulsion layer; a green-sensitive emulsion layer; and a blue-sensitive emulsion layer on a support wherein at least one of the layers is comprised of a plurality of additional layers. Two or more of the additional layers are direct reversal photographic emulsion layers of higher and lower sensitivity which are not previously fogged. The emulsion layer having lower sensitivity has a gradation of 1.8 or more resulting in a hard tone.

Abstract: An incorporated-dye image forming coupler type multilayer multicolor photographic material comprising a support having thereon at least two silver halide emulsion layers each of which is sensitive to a different spectral wavelength range, with the silver halide emulsion layer which first receives light at image exposure being positioned so that the light is received through a non-sensitive hydrophilic layer containing a semidiffusible color coupler which forms a dye image having a substantially complimentary color to the sensitive wavelength range of the silver halide emulsion layer first receiving light at image exposure and which has a diffusion coefficient of from about 0.25 to 0.80 as defined by the relationshipdiffusion coefficient = D.sub.B /D.sub.Awherein D.sub.A is the color density formed by the color coupler where the color coupler is present in the same layer as silver halide particles, developed without imagewise exposure, and D.sub.
