  • Patent number: 11001683
    Abstract: The present invention relates to a curable composition and a use thereof and, more particularly, to a curable composition and a use thereof, the curable composition comprising: (a) a compound capable of being denatured to a quinone-based compound by oxygen; (b) an amine-based polymeric compound; and (c) an oxygen clathrate structure. The curable composition is rapidly cured and can be cured not only at an interface of a conventional film but also to the inside of the film, such that the curable composition has uniform physical properties throughout the entire film and excellent physical properties compared to a curing film obtained by curing at an existing interface.

  • Patent number: 9268066
    Abstract: This invention relates to a complex prism sheet which is configured such that heat-resistant coating layers are formed on both surfaces of a substrate layer, thus preventing wrinkling or curling of the complex prism sheet due to heat generated from a light source, and increasing concealment and electro-optic characteristics, ultimately improving properties of a light crystal display. This complex prism sheet can be usefully applied to television (TV) sets, monitors, notebook personal computers (NBPCs), etc., which are required to have heat resistance, slimness and concealment because of an increasing use of a light emitting diode (LED) light source these days.
