  • Patent number: 4927572
    Abstract: The decorative panel having an underlay or core layer and a decorative layer on one or both sides of the core. At least one of the two surfaces of at least the outermost layer of the panel comprises a synthetic resin of one or more radiation-polymerized components selected from unsaturated acrylates and methacrylates. This layer, when scratched, has a scratch resistance of at least 1.5 N and preferably 2 to 7 N (DIN 53 799, part 10). In the method for manufacturing the decorative panel, a liquid surface layer which includes the radiation-polymerizable components is applied onto an underlay and then polymerized by means of radiation. In a further step, the radiation-polymerized surface layer is pressed together with the underlay at an elevated temperature.
    Type: Grant

  • Patent number: 4789604
    Abstract: A decorative panel and method therefor. The decorative panel includes a core layer and layers which are decorated on one or both sides of the core layer. At least the outermost layer of the panel on at least one of the two surfaces of the panel is predominantly composed of a synthetic resin which can be one or more components polymerized by radiation and includes unsaturated acrylates and methacrylates. This layer is scratch-resistant at a scratch loading of at least 1.5N, preferably 2-7N (DIN 53,799, part 10) and has a low gloss corresponding to a reflectometer value of not more than 50 at an angle of incidence of 85.degree. (DIN 67,350).
