    摘要: An image receptor element for the dye diffusion transfer process contains an image-receiving layer, which has increasing dye absorption capacity with increasing distance from the light-sensitive layers. Such an image-receiving layer may be obtained by use of mordants in concentrations which increase with increasing distance from the light-sensitive layers or by use of at least two mordants of different dye absorption capacity, the mordant of higher dye absorption capacity being arranged in a partial layer of the image-receiving layer further away from the light-sensitive layers. Such image receptor elements provide higher dye densities with lower total concentrations of mordants.

    摘要: Color images are obtained by chromogenic development of a colorphotographic material comprising several differently spectrally sensitized silver halide emulsions and color couplers associated thereto, a hydrophobic cyan coupler being incorporated by means of a hydrophobic coupler solvent and a hydrophobic yellow coupler being incorporated without a coupler solvent, when a color developing composition is used comprising a hydrophilic and a hydrophobic color developer compound. The color images have good stability of the cyan partial image to tropical conditions and good lightfastness of the yellow partial image.
