Abstract
A laminate comprising a layer of a synthetic linear polyester, a plasticizer-free primer coating applied to at least one surface of the polyester layer and comprising a cross-linked composition comprising a polymer of at least one monomer selected from the esters of acrylic acid and methacrylic acid, and optionally acrylic and/or methacrylic acid, and at least one layer made from a plasticized vinyl chloride polymer composition which is bonded to the linear polyester layer through the intermediary of the primer coating. The primer coating preferably includes the condensation product of an amine with formaldehye to effect cross-linking.
