  • Patent number: 10906065
    Abstract: The invention of the present application is a laminate in which thermoplastic polyurethane is used, excellent antifouling and adhesion properties are obtained, and glue residue is minimized. The laminate is provided with a substrate film formed from thermoplastic polyurethane, and an adhesive layer formed on one surface side of the substrate film. The substrate film has a surface layer on the opposite side of the first surface, a mixture of the thermoplastic polyurethane and a curable resin composition being present in the surface layer. The content ratio of the curable resin composition is configured so as to gradually decrease from the surface of the surface layer towards the interior of the substrate film. The curable resin composition contains at least one fluorine compound selected from the group consisting of fluorosilsesquioxane and fluorosilsesquioxane polymers, and a curable resin. The adhesive layer has a surface roughness of 350-750 nm.

  • Publication number: 20180258323
    Abstract: Provided is a film for plastic restoration with which transparency of plastic having reduced transparency can be easily recovered. The film for plastic restoration has base material film formed of thermoplastic polyurethane; and adhesive layer formed on a first surface side of base material film. Adhesive layer is composed of at least one resin selected from an acrylic resin, a urethane-based resin, a rubber-based resin and a silicone-based resin. A refractive index of adhesive layer is 1.40 to 1.70. Surface roughness of adhesive layer is 350 to 750 nanometers.

  • Publication number: 20130011611
    Abstract: The present invention provides a laminate including an anti-reflection film and a protective film that is stuck on the surface of the anti-reflection film. The protective film is excellent in temporary adhesiveness and can be removed to leave few adhesives. The laminate of the present invention directs to a laminate comprising an anti-reflection film; and a protective film stuck on the anti-reflection film, wherein the surface of the anti-reflection film has multiple protrusions, the distance between two tips of adjacent protrusions being equal to or smaller than visible light wavelength, and the protective film includes a support film and an adhesive layer that is in contact with the anti-reflection film, the adhesive layer including an adhesive that contains a polymer having an olefin structure as a monomer unit.
