<p>A new dye-image receiving element for the Ag halide dye-diffusion transfer process comprises a hydrophobic support (I), a subbing layer coated on the suppert (II) and an image-receiving layer (III), where (II) is coated from an aq. compsn. comprising a polyester-polyurethane with remaining isocyanate gps. reacted with a cpd. with at least one active H atom and a carboxylic or sulphonate salt gp. to form an anionic polyester-polyurethane mordant with glycidyl gps., which can react with the active H gps. of gelatin. The mordant /gelatin ration is from 25:1 to 1:1 and the gelatin coverage is at least 0.1 g/m2. Also claimed is an embodiment comprising a vinyl polymer support, layers II and III and a resin cover sheet (IV) laminated to III. Pref. IV is polyethylene terephthalate coated with a resinous melt-adhesive layer, pref. of polyethylene.</p> |
