Abstract

Abstract A multilayer coated film structure comprises an undercoat layer provided on a predetermined surface, such as a surface of a vehicle body, an intermediate coat layer put on the undercoat layer, a final coat layer of one of melamine alkyd resin coating and melamine acrylic resin coating including an antioxidant within the range of 1.0 to 5.0% by weight and put on the intermediate layer, and a hyaline coating layer of fluorocarbon resin put on the final coat layer. As the case may be, the final coat layer further includes a surface conditioning agent.
