Patent number: 6387489Abstract: A decorative sheet arranged on the outside or inside of buildings is composed of a compression-molded core made from one or more core layers.

The pigments are uniformly distributed within the core layer, and their proportion by weight is from above 0 to 20% by weight of the mixture made from pigments and from wood fibers or cellulose fibers. The pigments are colorfast, and weathering of the wood fibers or cellulose fibers at the surfaces of the sheet causes the original coloration of the core surfaces to change so that, when dry, the core is covered by a gray-silver patina, but substantially regains its original coloration when wet.Type: GrantFiled: March 7, 2001Date of Patent: May 14, 2002Assignee: Trespa International B.V.Inventors: Remco Willemse, Alex Van de Wall, Henricus Kömhoff
