    • A carrier film of thermoplastic polyester has releasable metal adhesive properties suitable for a metal transfer in which the polyester film is metalized and the metal layer is subsequently transferred to a permanent adhesive-coated substrate. The metal layer is in direct contact with the polyester carrier film and no intermediate release layer is present. Desired metal adhesion is provided by dispersing an suitable surfactant, and optionally, a hydrocarbon wax, uniformly into the polyester film. Surfactant on the outer surface of the carrier film modifies metal adhesion to the polyester such that the metal can be removed in a metal transfer operation.
    • 热塑性聚酯的载体膜具有适用于金属转移的可释放的金属粘合性能,其中聚酯膜被金属化,并且金属层随后转移到永久性粘合剂涂覆的基材上。 金属层与聚酯载体膜直接接触,并且不存在中间释放层。 通过将合适的表面活性剂和任选的烃蜡均匀地分散在聚酯膜中来提供所需的金属粘合。 载体膜的外表面上的表面活性剂改变了对聚酯的金属粘合性,使得金属可以在金属转移操作中除去。
