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/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. At least one such sheet or continuous paper is placed as a surface layer on a base layer and bonded thereto.
