  • Publication number: 20100003523
    Abstract: A coated thermoplastic film can be subjected to printing to obtain a decorative film, preformed (for example, thermoformed), and then inserted into a mold that has the configuration of the preformed decorative film. A base polymeric structure comprising a polymer such as a polycarbonate or blend thereof can be injection molded to the exposed surface of the preformed decorative film. The molded structure has various applications such as cell phones or other electronic devices, automotive vehicles, appliances, display panels, lenses, etc. A process for making the molded article is also described. The coating for the coated thermoplastic film can be made from a UV-curable composition and can provide superior embossing and thermoformability, hardness, and adhesion, while providing enhanced chemical, scratch and abrasion resistance.
