<p>A three-dimensional relief plastic sheet for use on articles such as binders comprises a decorative overlay sheet made of a plastics material and at least one three-dimensional relief representation integrally formed on the overlay sheet, for instance, by vacuum forming. The overlay sheet is adapted to be mounted to various articles, preferably made of plastics materials, by way of adhesives, heat-sealing, high-frequency welding, etc. The overlay is preferably made of PVC or styrene and thus can be secured, for example along the periphery thereof, to the vinyl covering of loose-leaf binders and other document carrying folders respectively using high-frequency welding and glues. The three-dimensional representation and the overlay sheet typically include colored sections and possibly transparent sections. A mirror-like backing sheet is provided behind the overlay sheet when there are such transparent sections.</p> |
