Abstract
Color prints are prepared in the form of retained images by the dye diffusion transfer process using a photographic recording material comprising in that order a transparent layer support, a light-sensitive element containing at least one silver halide emulsion layer and a non-diffusing color-providing compound associated thereto, a light-reflecting opaque layer and a mordant layer. The recording material is subjected to imagewise exposure through the transparent layer support. During development a colored moiety is released from the color-providing compound in imagewise distribution and transferred to the mordant layer. Silver and silver halide is removed by bleaching and fixing. The colored color-providing compounds retained in the light-sensitive element in imagewise distribution complementary to the transferred colored moiety form the color image visible through the transparent layer support against the light-reflecting background of the opaque layer. The mordant layer prevents contamination of the developer by diffusible dyes.
