Abstract
An ink-jet recording element is provided comprising a polymeric film substrate or a resin coated paper substrate and at least one ink-receiving layer coated thereon comprising at least one binder and at least one mordanting agent characterized in that said mordanting agent comprises a polymer containing a phosphonium moiety. Preferably said mordanting agent consists of a copolymer of ethylenically unsaturated monomers containing a phosphonium moiety co-polymerized with N-vinyl imidazole or 2-methyl-2-vinyl imidazole and optionally other co-polymerizable monomers or of a mixture of from 5 to 70% by weight, of a polymer containing a phosphonium moiety, 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 co-polymerization of N-vinyl imidazole or 2-methyl-2-vinyl imidazole and optionally other co-polymerizable monomers.
