ABSTRACT:
An image receptor layer suitable for the production of dye diffusion images with improved light fastness contains, as mordant, a mixture of from 5 to 70%, by weight, of a polymer containing cationic groups and obtained by homo- or co-polymerization of ethylenically unsaturated monomers and from 30 to 95%, by weight, of a second polymer, which is free from cationic groups and has been obtained by homo- or statistical co-polymerization of N-vinyl imidazole or 2-methyl-2-vinyl imidazole and optionally other co-polymerizable monomers.
