    • Sheet materials according to the present invention comprise a sheet material substrate, such as for example a film or paper sheet, with a polymer base coating overlying and adhered to a surface of the sheet material substrate. The base coating comprises a radiation cured crosslinked polymer derived from at least one vapor deposited acrylate prepolymer composition having a molecular weight in the range of from about 150 to 600. A metal layer is deposited on and overlies a surface of the base coating, and a polymer top coating overlies and is adhered to a surface of the metal layer. The top coating comprises a radiation cured crosslinked polymer derived from a vapor deposited acrylate prepolymer composition having a molecular weight in the range of from about 150 to 600 and a ratio of its molecular weight to its number of acrylate groups (MW/Ac) in the range of from about 150 to 600. According to one embodiment of the invention, metallized paper sheet materials are produced with superior appearance and performance characteristics which can be tailored to specific end use applications. For example, the metallized paper can be produced with a very shiny, high gloss surface appearance, and/or a high quality metallized layer free of defects or pinholes, and/or an outer surface which is highly receptive to printing.
    • 根据本发明的片材包括片材基材,例如薄膜或纸片,聚合物基底涂层覆盖并粘附到片材基材的表面。 基底涂层包含衍生自分子量为约150至600的至少一种气相沉积的丙烯酸酯预聚物组合物的辐射固化的交联聚合物。金属层沉积在基底涂层的表面上并覆盖在基底涂层的表面上, 聚合物顶涂层覆盖并粘附到金属层的表面。 顶涂层包含辐射固化的交联聚合物,其衍生自分子量在约150至600范围内的气相沉积的丙烯酸酯预聚物组合物和其分子量与其丙烯酸酯基团数(MW / Ac)之比 范围为约150至600.根据本发明的一个实施方案,生产具有优异的外观和性能特征的金属化纸片材料,其可以针对具体的最终用途应用而定制。 例如,金属化纸可以以非常光泽,高光泽的表面外观和/或没有缺陷或针孔的高质量金属化层和/或高度接受印刷的外表面制造。
