Abstract
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, …
