Abstract
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.
