  • Patent number: 9522983
    Abstract: A biaxially oriented composite film includes a polyester substrate supporting one or more coatings on one or both surfaces of said substrate, wherein the polyester substrate is a biaxially oriented film; wherein the one or more coatings is/are derived from a predominantly inorganic hardcoat coating composition including inorganic particles contained in a polymerisable predominantly inorganic matrix; and wherein the biaxially oriented composite film has been annealed at a temperature Ta (° C.) above Tg where Tg<Ta?Tg+100 (° C.) for a time t after thermal equilibrium where 1 hour ?t?72 hours. A method of making the film is provided.
    Type: Grant

  • Patent number: 7101825
    Abstract: A thermal transfer printing receiver sheet for use in association with a compatible donor sheet, the receiver sheet comprising a receiving layer to receive a dye thermally transferred from the associated compatible donor sheet, and further comprising a release medium and adhesion-promoting medium and an antistatic medium, wherein said release medium, said adhesion-promoting medium and said anti-static medium are, independently, present as a coating on at least part of at least one surface of the receiving layer or present in the receiving layer; use thereof as a clear printable overlaminate; and a laminated multilayer film comprising one or more of said receiver sheet(s) and a backing sheet comprising a film-forming material.
