  • Patent number: 7833588
    Abstract: The transparent conductive laminate of the invention is a laminate comprising a film made of a polymer with a photoelastic constant of no greater than 70×10?12 Pa?1, a light-scattering layer with a haze value in the range of 0.2-1.4% formed on one side thereof, and a transparent conductive layer formed on the other side thereof, wherein the laminate exhibits an overall retardation of ?/4. By using the laminate it is possible to provide touch panels with reduced light reflection, no coloration, excellent visibility and high reliability for outdoor use, as well as touch panel-equipped liquid crystal displays employing them.

  • Patent number: 7807261
    Abstract: A transparent conductive laminate consisting of a transparent polymer substrate, an uneven cured resin layer formed on at least one side of the substrate and a transparent conductive layer formed on the cured resin layer directly or through another layer. The cured resin layer contains fine particles A having an average primary particle diameter of 0.5 to 5 ?m and super fine particles C having an average primary particle diameter of 100 nm or less made of a metal oxide and/or a metal fluoride. The above transparent conductive laminate does not cause the deterioration of visibility by sparkling even when a transparent touch panel is mounted on a high-definition display and can prevent “Newton rings” which occurs between two transparent electrode substrates constituting the transparent touch panel.

  • Publication number: 20070224368
    Abstract: The transparent gas-barrier layered film of the present invention has a resin layer containing an acrylate resin having a lactone ring and a layer comprising an inorganic metal compound at least on one side of a macromolecular film. The transparent gas-barrier layered film has a high transparency and shows an excellent gas-barrier property against vapor. Therefore, it is able to be advantageously used as a substrate of, for example, electronic paper, liquid crystal display device, touch panel, organic light emitting diode element, filmy solar battery and electronic tag.
