  • Patent number: 9213311
    Abstract: The present invention provides a volume hologram transfer foil which has good foil cutting characteristics and is used to manufacture a volume hologram laminate by transferring a volume hologram layer to an adherend by thermocompression. The volume hologram transfer foil includes a base material, a protective layer, a volume hologram layer, and a heat seal layer, wherein the protective layer contains a hard coat component, a rupture elongation control component, and a foil cutting characteristic control component which has a thermal expansion coefficient different from those of the hard coat component and rupture elongation control component and is incompatible with the two components.

  • Patent number: 8497140
    Abstract: An encapsulant layer for a photovoltaic module enabling recovering and recycling or reusing of reutilizeable resources such as a transparent front face substrate and photovoltaic cell and the like among constituents of a photovoltaic module, and a method for manufacturing a regenerated photovoltaic cell and a regenerated transparent front face substrate. The photovoltaic module is formed by laminating: a transparent front face substrate; a photovoltaic cell carrying a wiring electrode and a takeoff electrode, and an encapsulant layer is placed on at least one surface; and a rear face protecting sheet. The encapsulant layer is a separable layer formed mainly of a thermoplastic resin, and an output maintenance factor of photoelectronic power of the photovoltaic module using the encapsulant layer is in a range of 80% to 100%.

  • Publication number: 20130182301
    Abstract: A primary object of the invention is to provide a volume hologram transfer foil which has good foil cutting characteristics and is used to manufacture a volume hologram laminate by transferring a volume hologram layer to an adherend by thermocompression. The above problem is solved by a volume hologram transfer foil comprising a base material, a protective layer formed on the base material, a volume hologram layer formed on the protective layer and having a volume hologram recorded, and a heat seal layer formed on the volume hologram layer, wherein the protective layer contains a hard coat component formed of an ionizing radiation-curable resin, a rupture elongation control component which improves the rupture elongation of the protective layer, and a foil cutting characteristic control component which has a thermal expansion coefficient different from those of the hard coat component and rupture elongation control component and is incompatible with the two components.
