Abstract: Disclosed is a side protective moulding having a decorative section and a rib section. The decorative section has a protruding section protruding most with respect to a door, and a curved section extending aslant from the protruding section toward the door. The rib section has a hollow section formed on the back side of the protruding section and a reinforcing leg section extending from the hollow section toward the door. The side moulding is moulded by a hollow injection moulding process. Adopting this moulding process can improve the outside appearance of the side moulding by eliminating sink marks and wrinkles from the surface of the decorative section if a thick wall section for increasing side moulding rigidity and impact strength is formed on the back side of the decorative section.

Abstract: A method of producing a united product composed of a glass plate and a vinyl chloride resin molded body, which comprises the steps of conducting a preliminary treatment of the periphery of the glass plate for enhancing adhesion; applying a polyamide resin adhesive including silane compound to the preliminarily treated periphery of the glass plate; disposing the glass plate within a cavity of an injection mold; injecting a molten vinyl chloride resin around the periphery of the glass plate within the cavity after clamping the injection mold; and cooling the injection mold, thereby bonding the glass plate and the vinyl chloride resin molded body. And a united product having excellent water resisting qualities, which comprises a glass plate; a vinyl chloride resin molded body; and an epoxidated polyamide adhesive.
