摘要:
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.

This invention is concerned with security paper (3) for bank notes, cheques and like documents in a security strip of enhanced security which is more difficult to counterfeit than the present bank notes containing window threads. Security papers according to the invention comprise at least one elongated security element (4) which security element is partially embedded within said paper with portions thereof being exposed at the surface of the paper at spaced intervals along the length of the security element at windows in the paper, said security element being visually detectable in transmitted light and being visible in the windows of the paper in reflected light, wherein the said security element comprises a plurality of layers including a support layer (11) and metallic regions (12) such that when the exposed portions of the security element are viewed in reflected light there is visible to the unaided eye in each window at least two metallic areas (1, 2) which form repeating patterns along the length of the element, with the said metallic areas being of different colour.

A backup sheet for backing a worksheet during a small bore drilling process comprises a layer (20,22) of polyimide, fluorocarbon or high temperature polycarbonate material on at least one side of a core (10,12,14,16,18).
摘要:
A metal-polypropylene laminate composite comprising a polypropylene sheet made of a blend of a modified polypropylene prepared by modifying a crystalline polypropylene with an unsaturated carboxylic acid or its derivatives or a crystalline polypropylene containing such a modified polypropylene, with 15 to 50 wt.% of waste paper, organic fibers or wood pulp and metal plates superposed on and bonded by hot forming to both the surfaces of said polypropylene sheet is provided. It is of light weight and useful in acoustically sound absorption, vibration damping and heat insulation purpose.

摘要:
Described is a sealed container material having a deoxidation function comprising a metallic base material reactive with oxygen and a hydrophilic coating layer of water-soluble polymer such as hydroxyethyl cellulose formed on the surface of the metallic base material. An oxygen- and moisture-permeable coating layer composed of a silicone resin or an olefin resin may further be provided on the hydrophilic coating layer. The material exhibits excellent oxygen absorbing ability and is thus suited as a material for sealed containers, such as cans, bottles, capsules etc., for encasing food, drink, chemicals, and medical drugs and storing them over a long period of time without denaturation or deterioration.
