Disclosed is a method for preparing a composite paint composition (a composition forming a coating film after the volatilization of a solvent) comprising urushiol extracted from raw lacquer. Specifically, the method comprises the steps of: mixing raw lacquer with an organic solvent and centrifuging the mixture to separate an urushiol layer dissolved in the organic solvent; heating the urushiol layer dissolved in the organic solvent so as to remove the organic solvent and water, thus extracting urushiol; mixing the extracted urushiol with composite paint to prepare a composite coating composition comprising extracted urushiol; and applying the composite paint composition comprising extracted urushiol to the surface of various materials, including wood, various plastics, metals, paper, fabrics or leathers, through various coating processes, including spray coating, roll coating, curtain coating, film coating, printing, dyeing or dipping, and curing the applied composition. Also disclosed are a composite paint composition comprising extracted urushiol, prepared according to said method, and an article coated with the composite paint composition comprising extracted urushiol. The article coated with the lacquer component urushiol, manufactured according to said method, is environment-friendly and beneficial to the health, because the lacquer component has a far- infrared ray-emitting effect, an electromagnetic wave-shielding effect and an excellent antimicrobial effect.
