Abstract
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° (DIN 67,350).
