ABSTRACT OF THE DISCLOSURE An improved process of making abrasion-resistant decorative laminate without overlay comprises simultaneously impregnating and coating a laminate decor sheet with a mixture of the liquid impregnating resin and an abrasion-resistant composition of microcrystalline cellulose and abrasion-resistant mineral particles such as alumina. The microcrystalline cellulose functions not only as a binder material in the product, but also serves to maintain the mineral particles in suspension in the liquid resin. The mixture is deposited onto the top surface of the decor sheet which absorbs the liquid resin leaving on the upper surface thereof an ultra-thin layer of the abrasion-resistant composition plus a small amount of resin. After drying, the decor sheet is ready for use in the manufacture of high and low pressure decorative laminates.
