Abstract
Abstract A decorative thermosetting laminate for floors with an extremely increased abrasion resistance comprising a base layer, at least two decor sheets of paper and possibly at least one non-decorative paper sheet, all these paper sheets being impregnated with a thermosetting resin and firmly bonded to the base layer. The paper material of these sheets being transparent and at least one of the decor sheets or non-decorative transparent paper sheets being provided with a resin coated surface having small hard particles evenly distributed over said surface, wherein a non-decorative paper sheet may be placed as the uppermost sheet in the laminate on top of the decor sheets.
