  • Patent number: 6790914
    Abstract: A film for a display device produced by using a transparent (crosslinked) resin film formed of a composition including a cyclic olefin addition copolymer of the present invention has optical transparency, heat resistance, liquid crystal resistance, dimensional stability, and adhesion and is suitably used as an alternative to a glass substrate of a liquid crystal display device and an EL display device. The transparent (crosslinked) resin film can be used as a polarizing film, surface protective film, retardation film, transparent conductive film, light diffusion film, film for an EL display device, transparent conductive composite material, antireflection film, and the like.

  • Patent number: 6639021
    Abstract: A composition comprising a cyclic olefin addition copolymer containing recurring units of the following formulas (1) and (2), and at least one compound selected from (A) a compound acting as an acid when heated to 50° C. or higher, (B) a metal compound of an alkoxy compound, aryloxy compound, carboxyl compound, &bgr;-diketone compound, halogen compound, or oxide, (C) an organic carboxylic acid, organic phosphoric acid, organic sulfonic acid, ammonia, primary to tertiary amine compound, or quaternary ammonium hydroxide compound. The composition exhibits excellent optical transparency, solvent resistance, dimensional stability, heat resistance, and adhesion to metals and inorganic materials, and suitable for use in optical transparent materials and electronic material parts, to a cross-linked product obtained by crosslinking the composition via siloxane bonds, and to a film, sheet, or coating made from the composition.
