Abstract
The present invention provides a method for coating an aluminum wheel using a coating composition capable of forming a coating film having a superior cosmetic property as well as an anticorrosive property much enough for preventing corrosion even in the use in an area where the coating film is susceptible to salt damage, and an aluminum wheel obtained by the method. A method for coating an aluminum wheel including applying an anticorrosive coating composition onto the aluminum wheel, and thereafter applying a clear coating composition to form a transparent multilayer coating film, wherein the anticorrosive coating composition contains an acrylic resin (1) having a weight average molecular weight of 50,000 to 140,000, a glass transition point of 20 to 50° C., a hydroxyl value of 10 to 50 mgKOH/g, and an acid value of 10 to 40 mgKOH/g, and an epoxy resin (2) having an epoxy equivalent of 210 to 1,000 g/eq and contains the epoxy resin (2) in an amount of 5 to 20 parts by weight on the solid matter basis to 100 parts by weight of the solid matter of the acrylic resin (1).
