Abstract: The front surface of a wooden overlay sheet having a wood material on the front surface is subjected to a color treatment with a colorant. A resin-based primer is then applied to the colored front surface and a transparent resin layer is then formed on the resin-based primer.

Abstract: Thick molded strips of unsaturated polyester resin are bonded to butt edges of a panel member, upper and lower edge portions of the thick molded strips are cut so as to make upper and lower edge surfaces coplanar with upper and lower surfaces of the panel member, the coplanar surface is, thereafter, coated with the unsaturated polyester resin, and the polyester resin film and the thick molded strips are, finally, trimmed with a polisher; even though the molded strips are decreased in thickness through the polishing, the molded strips are thick enough to make the butt edges of the panel invisible, and the appearance of the board member is improved.

Abstract: The front surface of a wooden overlay sheet having a wood material on the front surface is subjected to a color treatment with a colorant. A resin-based primer is then applied to the colored front surface and a transparent resin layer is then formed on the resin-based primer.

Abstract: The front surface of a wooden overlay sheet, having a wooden material on the front surface thereof, is subjected to a color treatment with a colorant comprising a primer resin; the wooden overlay sheet, which was subjected to color treatment, is positioned in a metal mold for molding, and a transparent resin layer is molded on the front surface thereof by means of injection-molding. Furthermore, a synthetic resin core material is molded on the rear surface of the wooden overlay sheet. A composite molded article is thereby produced, wherein a synthetic resin core material is molded on the rear surface of the wooden overlay material, and a transparent resin layer is molded on the front surface of the wooden overlay sheet. Thus, the present invention enables the enhancement of the outer appearance of the product and the enhancement of the adhesion of the wooden overlay sheet and the transparent resin layer.

Abstract: A composite molded article is formed by forming a composite wood overlay surface material by laminating a wood veneer on a front side of a base sheet selected from one of a metal sheet and a resin sheet; laminating a back sheet selected from one of a porous material and a fibrous material on a back side of said base sheet; coating said wood veneer incorporated in said composite wood overlay surface material; placing said composite wood overlay surface material in a mold; and injecting a resin onto said back sheet incorporated in said composite wood overlay surface material. Thus, the composite molded article has an excellent appearance of coating on the surface of the article.

Abstract: The present invention is related to a production method for a composite molded article. The method comprises the steps of: forming a composite wood overlay surface material by laminating a wood veneer on a front side of a base sheet selected from one of a metal sheet and a resin sheet; laminating a back sheet selected from one of a porous material and a fibrous material on a back side of said base sheet; coating said wood veneer incorporated in said composite wood overlay surface material; placing said composite wood overlay surface material in a mold; and injecting a resin onto said back sheet incorporated in said composite wood overlay surface material. Thus, the present invention provides a composite molded article having an excellent appearance of coating on the surface of the article and automation of the coating step is possible.

Abstract: A composite molded article comprising a layer 5 made of a synthetic resin on which is laminated a surface material 1 having a construction such that wood veneers 3 and 4 are laminated on the surfaces of a metal sheet 2. A method for molding a composite molded article comprises the steps of: arranging, in a metal mold 7 for molding, a surface material 1 which has a construction such that wood veneers 3 and 4 are laminated on each surface of a metal sheet 2; and molding a synthetic resin 5 on a backside of the surface material 1 to integrate the surface material 1 with the synthetic resin 5.

Abstract: A slat for blinds such as Venetian blinds made up of a core plate made of metal, FRP or wood and a pair of surface layers laminated on both faces of the core plate via intermediates. The laminated construction well suppresses generation of harsh noises otherwise caused by slat colliding and dewing even when used in wet environments.

Abstract: In production of a decorative article from piece board of a decorative plywood, a decorative sheet for the decorative plywood is formed by heat pressing a powdery sheet on a material sheet in order to simplify coating process.

Abstract: In production of resin-treated woody material, powdered resin coating on a wooden crude board is combined with subsequent heating under pressure, preferably with use of backings. Concurrent coating and hardening of the resin, and bonding of the backings greatly simplify the process and equipments.
