Abstract
Abstract The present invention pertains to embossed decorative patterns and decorative laminates, particularly textured film finished structural elements and the method of manufacture wherein a resilient material such as a wadding sheet or pad sheet is interposed between the surface film and the substrate. High quality uniformly embossed products of great durability are economically manufactured by this technique. The invention is particularly useful when the substrate is rigid or semi-rigid in physical characteristics or wherein the hardness varies across the surface of the substrate.
