IMPROVEMENTS IN INK-JET MEDIA OVERCOAT LAYERS |
摘要 |
An image-recording element for inkjet ink images comprises a support, an ink-receptive layer and a top layer, wherein the top layer comprises a polymer that contains both a hydrophilic component and a hydrophobic component, or a mixture of two or more such polymers, the said polymer or polymer mixture being present in the top layer in an amount of from 0.003 to 0.5 g/m<2>, and wherein the top layer has been hardened with an oxazoline functional polymer. The top layer preferably comprises a polymer that contains both hydrophilic substituents and hydrophobic substituents, for example a polymer selected from the polymers and copolymers of acrylic acid, methacrylic acid, acrylic acid esters or methacrylic acid esters, or a salt of such a polymer or copolymer. The base layer, which may comprise gelatin, preferably has a thickness of from 3 to 20 mu m. The support may be a conventional support, for example a paper sheet. The invention can provide improved drying times for the inkjet images, even under conditions of high humidity. |
