Abstract
Abstract A decorative laminate having a differential texture and a differential gloss, and a method of manufacture therefor, are provided wherein the laminate has an embossed surface comprising raised segments which contain PVC resin particles adjoining recessed segments which do not contain PVC resin particles whereby the raised and recessed segments impart a relief pattern on the surface of the decorative laminate, and the raised segments have a rougher surface texture and a lower gloss than the recessed segments. The decorative article is useful as a floor covering.
