  • Patent number: 4400423
    Abstract: An abrasion-resistant laminate is prepared by providing an ultra thin coating of micro-crystalline cellulose overcoated with an ultra thin layer of mineral particles and micro crystalline cellulose on the surface of conventional printed paper, followed by impregnating the paper with a conventional laminating resin, and then using the print paper so obtained in a laminating process without the necessity of using an overlay sheet.

    Inventors: Herbert I. Scher, Israel S. Ungar
  • Patent number: 4154882
    Abstract: A decorative high pressure laminate having registered color and embossing is produced by effecting simultaneous embossing and laminating using a three dimensional press plate acting against an overlay sheet containing high flow melamine resin and pigment, so that during the pressing operation the resin and pigment flows laterally from the high pressure areas to the low pressure areas with the result that the underlying print sheet is visible through the overlay sheet in the high pressure areas while the pigment in the overlay sheet in the low pressure areas mask the print sheet.
    Type: Grant
    Filed: February 10, 1978
    Date of Patent: May 15, 1979
    Assignee: Nevamar Corporation
    Inventors: Israel S. Ungar, Herbert I. Scher, Delbert A. Williams
  • Patent number: 4093766
    Abstract: A decorative high pressure laminate having registered color and embossing is produced by effecting a simultaneous embossing and laminating using a three-dimensional press plate acting against an overlay sheet containing high flow melamine resin and pigment beneath which lies a melamine resin impregnated print sheet and below that an underlay sheet containing high flow melamine resin and pigment of another color. During the pressing operation the resin and pigment in the overlay flow laterally from the high pressure areas to the low pressure areas with the result that the underlying print sheet is visible through the overlay sheet in the high pressure areas while the pigment in the overlay sheet in the low pressure areas masks the print sheet. In areas of even lower pressure the color from the underlay sheet strikes through to the surface to provide a third color.

  • Patent number: 4092198
    Abstract: A decorative high pressure laminate having registered color and embossing is produced by effecting simultaneous embossing and laminating using a three-dimensional sculptured press plate acting against an overlay sheet having therebeneath a print sheet having a coating containing a high flow melamine resin and pigment, so that during the pressing operation the resin and pigment coating flows laterally from the high pressure areas to the low pressure areas with the result that the underlying print sheet is visible through the overlay sheet in the high pressure areas while the pigment in the coating on the print sheet in the low pressure areas mask the print sheet.
