PURPOSE:To produce superior rust preventing power by synergism by adding a rust preventive and an ultraviolet absorber as principal components. CONSTITUTION:A rust preventive composition is composed essentially of 100pts. wt. rust preventive and 5-300pts.wt., especially 5-50pts.wt. ultraviolet absorber. One or more kinds of rust preventives selected among org. rust preventives such as amines, amides, imidazoles, triazoles and pyrazolones and inorg. rust preventives such as chromates, nitrites and silicates are used as said rust preventive. One or more kinds of ultraviolet absorbers selected among benzophenone type ultraviolet absorbers and piperidine type ultraviolet absorbers are used as said ultraviolet absorber.
