Abstract
An ink jet recording media system is described which comprises at least one coating layer that comprises a copolymer or cooligomer, which copolymer or cooligomer comprises monomer units derived from at least one monomer selected from the group consisting of the acrylate and acrylamide monomers, at least one monomer selected from the group consisting of the amine containing ethylenically unsaturated monomers and at least one monomer selected from the group consisting of the polyacrylates of polyols. The copolymer or cooligomer is at least partially neutralized with acid. The media system exhibits excellent dye wash fastness, fast dry times, high gloss and excellent light fastness.
Claims41
