ABSTRACT:
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.
