Abstract: Process for the production of a decorative thermosetting laminate with an abrasion-resistant surface layer, which laminate comprises paper sheets impregnated with a thermosetting resin. In the process a continuous paper is impregnated with a noble thermosetting resin such as melamine-formaldehyde resin. At least one side of the paper is coated with 2 - 20 g/m , preferably 3 - 12 g/m of small, dry and hard particles evenly distributed over the whole wet surface of the resin on the continuous paper. The resin is dried, whereupon the particle coated impregnated paper, so-called prepreg is possibly cut to sheets. At least one such sheet or continuous paper is placed as a surface layer on a base layer and bonded thereto.

Abstract: A decorative thermosetting laminate with an extremely increased abrasion resistance comprising a base layer and at least two patterned decor sheets of paper impregnated with a thermosetting resin and firmly bonded to the base layer. The paper material of these decor sheets is transparent. These sheets are provided with the same pattern and placed on top of each other in such a manner that the corresponding parts of the pattern of the sheets coincide at least mainly but preferably fully with each other, whereby the pattern at abrasion of one decor sheet will be repeated in the next decor sheet.

In the process a continuous paper is impregnated with a noble thermosetting resin such as melamine-formaldehyde resin. At least one side of the paper is coated with 2 - 20 g/m2, preferably 3 - 12 g/m2 of small, dry and hard particles evenly distributed over the whole wet surface of the resin on the continuous paper. The resin is dried, whereupon the particle coated impregnated paper, so-called prepreg is possibly cut to sheets.
