Abstract
A contrasting color is imparted to the decorative surface of a decorative laminate by inserting a pigment coated release sheet between the molding caul and the decorative surface during the molding operation, with the pigment facing the decorative surface. Upon application of heat and pressure during the formation of the laminate, color is transferred from the release sheet to the decorative surface. A suitable technique is also used to emboss or impart surface texture to the decorative surface during molding. Thereafter, the textured surface is subjected to rubbing or brushing to remove more color from the embossed or raised areas than the debossed areas, thereby highlighting or imparting a shaded effect to the textured surface.
