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.
