  • Curable acrylic coatings for exterior laminate
    Publication number: 20040089409
    Abstract: The present invention relates to providing a protective acrylic coating to a laminate surface. More particularly, the present invention provides said protective acrylic coating to a laminate surface via a release sheet. The release sheet allows application of a substantially solid acrylic compound to a laminate surface of a laminate assembly. The substantially solid acrylic compound may be cured during thermal and pressure processing of the laminate assembly. Also, the cured acrylic coating protects the laminate surface from fading and from damage.

  • Electroluminescent high pressure laminate
    Patent number: 6468677
    Abstract: The invention relates to laminates including at least a first resin impregnated sheet having an electroluminescent compound dispersed therein and electrical leads coupling the electroluminescent compound to a source of electrical energy. The laminate is manufactured by applying an electroluminescent compound to a first resin impregnated sheet, applying electrical leads to the first sheet for the selectively application of electrical energy and heating and pressing the first sheet.
