ABSTRACT:
An image receiving material suitable for image production by dye diffusion transfer processing controlled by the development of (an) image-wise exposed silver halide emulsion layer(s), wherein the support of said material is a resin support coated with gelatin in admixture with a cationic polymeric mordant containing glycidyl groups that can react with active hydrogen atoms of the gelatin, wherein said support is made of a vinyl chloride polymer and said support is coated with an image receiving layer wherein the weight ratio of said polymeric mordant to gelatin is from 25:1 to 2.5:1, and the gelatin coverage is at least 0.1 g per m2. In a particular embodiment the image receiving layer is used in the production of a laminar article serving as identification document.
