The present invention relates to an integral-skin foam molded article which includes: a main body of the molded article comprising a flexible urethane foam molding material; and a coating layer comprising a polyurethane coating material formed on the surface of the main body of the molded article, either or both of said urethane foam molding material and coating layer containing one or more of an inorganic or organic antibacterial agent. This integral-skin foam molded article can maintain an anti-fungal and anti-bacterial action for a significantly long period of time and therefore does not undergo discoloration.

Foam molded article with integral skin having an antibacterial effect

A polyurethane material for decorative parts is disclosed which is a tow-liquid type material comprising a polyol component and an isocyanate component and having a stabilizer incorporated in the polyol component. The stabilizer is a ternary system of a specific hindered amine type ultraviolet stabilizer, a specific hindered phenol type antioxidant, and a specific benzotriazole type ultraviolet absorbent or acrylontrile type ultraviolet absorbent. A transparent synthetic resin part formed by potting this polyurethane material on the upper surface of a base excels in weatherability and lightfastness. Thus, the present invention provides decorative parts which retain good appearance for a long time.

Polyurethane material for decorative parts

This invention is directed to a leather-wrapped steering wheel which has a core-covering part of low hardness and high repulsion elasticity and, therefore, permits a leather wrap part to be formed through no medium of any rubber layer. This steering wheel comprises a core, a core-covering part made of semirigid urethane foam, and a leather wrap part covering the core-covering part. The semirigid urethane foam is produced by the reaction injection molding of a urethane foam material for water molding using a polyether tape compound and/or a polymer polyol type compound as a polyol moiety and a MDI type compound as a polyisocyanate moiety. This semirigid urethane foam possesses hardness in the range of 40 to 65 (Asker C), repulsion elasticity in the range of 15 to 60%, and density in the range of 0.3 to 0.5 g/cm.sup.3.
