    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.

    Abstract: A method is provided for enhancing the gas barrier properties of substrates such as materials used in packaging, by applying a composition comprising a vinyl alcohol / vinyl amide copolymer, a cross-linker and, optionally, a diacrylate or other polyacrylate and a photoinitiator to the material and curing the composition by irradiation with UV light, visible light, IR irradiation and/or electron beam or by exposure to heat. The method includes the optional step of subjecting the material to a low-temperature plasma discharge or a corona discharge prior to applying the composition. The method provides, for example, packaging materials, such as, flexible packaging materials such as plastic films producing packaging materials with excellent gas barrier properties which are readily printed upon.
