Decorative sheet and processes for the production of sheets

A process for producing sheets comprising the steps of:

• placing one or more mechanically precompacted layers made from cellulose fibers or from wood fibers, enclosed by a hot-curing resin, one on top of another layer and press-molding the layers with one another, applying heat to the layers to bind them together to a core, curing the resin within the core, introducing the pigments into the resin prior to resin-coating the cellulose fibers or wood fibers within the mechanically precompacted layers, and wherein the fibers at the surfaces of the core layer of the produced sheets undergo changes on weathering, resulting in a patina effect.
