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 said image-receiving material contains a hydrophobic resin support coated with a subbing layer that is coated with an image-receiving layer containing gelatin in combination with a cationic polymeric mordant containing glycidyl groups that can react with active hydrogen atoms of gelatin, the weight ratio of said polymeric mordant to gelatin being 25:1 to 1:1 and the gelatin being present at a coverage of at least 0.1 g per m2, and wherein said subbing layer has been applied from an aqueous composition comprising a polyester-polyurethane wherein isocyanate groups still present in its structure have reacted with an ionomeric compound containing at least one active hydrogen atom and a carboxylate or sulphonate salt group.
