This invention relates to a 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.sup.2, preferably 3-12 g/m.sup.2 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.
Process for the production of a decorative thermosetting laminate with an abrasion-resistant surface layer, said laminate comprising paper sheets impregnated with a thermosetting resin, said process comprising impregnating a continuous paper with a thermosetting resin, and having the surface of the paper wetted with said resin coating at least one side of the continuous paper with 2-20 g/m.sup.2 of small, dry and hard particles so that said particles are evenly distributed over the surface of resin on the continuous paper, then drying the resin with the particle coated thereon, cutting the particle coated impregnated paper into sheets, placing at least one such paper sheet as a surface layer on a base layer and bonding the surface layer to the base layer.
Process for the production of a decorative thermosetting laminate with an abrasion-resistant surface, said laminate comprising paper sheets impregnated with a thermosetting resin, said process comprising impregnating a continuous paper with a thermosetting resin, and leaving the surface of the paper wetted with said resin, coating at least one side of the continuous paper with 2-20 g/m.sup.2 of small, dry and hard particles so that said particles are evenly distributed over the surface of resin on the continuous paper, then drying the resin with the particles coated thereon, placing at least one such continuous paper as a surface layer on a base layer and bonding the surface layer to the base layer.
