Abstract:
A sheet material comprising:a sheet material substrate;a polymer base coating overlying and adhered to a surface of said sheet material substrate, said base coating comprising 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 deposited on and overlying a surface of said base coating; anda polymer top coating overlying and adhered to a surface of said metal layer, said top coating comprising 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,wherein said prepolymer composition for said top coating includes a polar acrylate monomer having a dielectric constant of higher than four.
