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.

L'invention concerne un système de supports d'enregistrement à jet d'encre comportant au moins une couche de revêtement contenant un copolymère ou un cooligomère. Le copolymère ou cooligomère contient des unités monomères dérivées d'au moins un monomère choisi dans le groupe composé de monomères acrylate et acrylamide, d'au moins un monomère choisi dans le groupe composé de monomères à insaturation éthylénique contenant amine, et d'au moins un monomère choisi dans le groupe composé de polyacrylates de polyols. Le copolymère ou cooligomère est au moins partiellement neutralisé avec de l'acide. Le système de supports selon l'invention présente une excellente résistance au lavage de colorants, des durées de séchages réduites, une grande brillance et une excellente résistance à la lumière.
