Abstract
The decorative sheets and decorative boards of this invention each comprise a laminated structure which includes a first sheet of fibrous material (such as Japanese paper, kraft paper, tissue paper or impregnated paper), a first heat-sealable resinous layer (such as polyethylene or polypropylene), a sheet of metal foil (such as aluminum or iron), a second heat-sealable resinous layer (such as polyethylene or polypropylene) and a second sheet of fibrous material (such as Japanese paper, kraft paper, tissue paper or impregnated paper), with a precious-wood layer bonded to the surface of the laminated structure. For decorative boards, a base material (such as a plywood) is bonded to the back surface of the laminated structure, through an adhesive layer of a cold-curable, thermosetting or thermoplastic resin, by hot pressing, cold pressing or a combination thereof. The decorative sheets and decorative boards preferably are manufactured by a process of melt-extrusion laminating.
