  • Patent number: 9096921
    Abstract: The present invention provides a transparent conductive film excellent in pen sliding durability at the time of using the transparent conductive film for a touch panel and which enables to production a touch panel having excellent flatness. A transparent conductive film of the present invention comprises a transparent plastic film base and a transparent conductive thin film containing crystalline indium oxide as a main component laminated on at least one face of a transparent plastic film base, wherein an average circle-equivalent diameter of crystal grains of indium oxide of the transparent conductive thin film is 30 to 1000 nm, and a coefficient of variation of a circle-equivalent diameter of the crystal grains is 0.00 to 0.30. The transparent conductive film preferably contains indium oxide containing 0.5 to 8% by mass of tin oxide.

  • Patent number: 7812623
    Abstract: A transparent conductive film roll which has a transparent conductive layer on at least one surface thereof and has an excellent distribution uniformity of surface resistance in longitudinal and lateral directions thereof wherein the distribution uniformity D of surface resistance defined by the following expression (1) is 0.2 or less when the surface resistance of the transparent conductive layer is measured at a total of 33 points within the film roll, and therefore, is suitable especially for a large panel, D=(Rmax?Rmin)/(Rmax+Rmin)??(1) where Rmax and Rmin represent the maximum and minimum values of 33 surface resistance measurement values.

  • Patent number: 5856017
    Abstract: The present invention provides a gas barrier film including a plastic film and a thin film which is made of a composition containing an oxide as a main component and is formed on at least one surface of the plastic film. A specific gravity of the thin film is 55% or more and 100% or less of a specific gravity of the oxide in the form of a crystal generally present at room temperature and under atmospheric pressure. Thus, the invention provides a gas barrier film having an excellent gas barrier and retort properties and bending resistance; a gas barrier film suitably used in a wrapping material for dried food, liquid food or food containing liquids, frozen food and retort food; a gas barrier film that can be used in an electronic oven, can be sterilized by micro waves and can contain a free-oxygen absorber; a gas barrier film suitably used in a paper carton, a tube, a lid and the like; and a gas barrier film suitably used for cutting off gas for industrial use.
