<p>A metallised film has a substrate layer (1) of a synthetic polymeric material, and on at least one surface (3, 5) thereof an adherent layer (4, 6) of an acrylic or methacrylic copolymer, the copolymer comprising (a) a comonomer selected from acrylic acid, methacrylic acid or a derivative of acrylic acid or methacrylic acid, (b) a copolymerisable sulphonated ethylenically unsaturated comonomer, and optionally (c) an additional comonomer, said comonomers (a) and (b) being present in the respective molar percentages in the ranges (a) 26 to 99% and (b) 1 to 50%. A metallic layer (2, 7) is on the surface of the at least one adherent layer, remote from the substrate.</p> |
