The invention discloses a method for producing an acrylic anodic electrophoretic coating with high weatherability. Functional resins are added in the synthetic basic materials; the advanced interpenetrating network copolymerization technology route and the technical treatment methods are adopted; and the resins having different functions are organically bonded so that the parts, corresponding to the main absorption peak of light, of the anionic acrylic resins synthesized through reaction are in the range of the solar spectrum, thus improving the light fastness and the outdoor aging resistance of the coating. In addition, the problems of color instability and discoloration of the coating are solved and the coating can be used not only as the primer but also as the primer-topcoat coating.
