Abstract
Disclosed is the preparation of a laminated composite structure. Such laminate composites comprise a base layer comprising a base substrate; at least one polymeric layer laminated onto a surface of the base substrate. The polymeric layer is preferably decorative on an exterior surface and is preferably bonded to the base substrate using a thermosetting adhesive interposed between the substrate surface and the polymeric layer. The polymeric layer comprises an opaque, polymeric, e.g., polypropylene-based, film which has a cavitated core and a coating thereon, which is preferably an acrylic-based coating applied to both sides of the film. Such laminated structures can be produced by passing the requisite base layer, polymeric layer film and adhesive through sets of rollers or drums which supply the heat and/or pressure needed to adhesively bond the layers together.
