A metallised film comprises a metallised layer (2) bonded to a thermoplastic polymeric substrate (1) by an adherent layer (4) comprising a sulphonated polyester resin and an ethoxylated alkyl phenol. A polyester such as biaxially orientated polyethylene terephthalate, is a preferred substrate. The films exhibit improved bonding of the metallised layer to the substrate which bonding may be further enhanced by the inclusion of fine particulate filler in the adherent layer, and are of utility in diverse applications including decorative drapes, magnetic recording media and the packaging of liquids. |
