发明名称 Dye image receiving material.
摘要 An image receiving material suitable for image production by dye diffusion transfer processing material controlled by the development of (an) image-wise exposed silver halide emulsion layer(s), wherein said image receiving material comprises a supported image receiving layer free from gelatin and containing (1) a cationic polymeric mordant, and (2) colloidal silica applied from an aqueous acidic colloidal sol having a pH of not more than 4, and containing hydrated silica in combination with a smaller amount of colloidal alumina, the amount of said colloidal material to said mordant in the image-receiving layer being in a weight ratio range from 1/5 to 1/2, and silica (SiO2) being present at a coverage of at least 0.5 g per m2.
