PROBLEM TO BE SOLVED: To provide an aqueous coating composition that, in the case where the coating film formed by the aqueous coating composition on a rubber member such as a vibration insulating mount or the like peels off by vibration during the transportation of automobiles by land and sticks to a topcoat film coated on a roof portion, a bonnet portion or the like of an automobile body, prevents the contamination such as the yellowing or the like of the topcoat film, a method for preventing the contamination and a coated article produced by the method. SOLUTION: The aqueous coating composition comprises an acrylic modified epoxy ester resin, a methyl etherified melamine resin or a mixture of a methyl etherified melamine resin with a butyl etherified melamine resin and a pigment, wherein the weight ratio in solid content of an epoxy resin (a)/a fatty acid (b)/ an ethylenically unsaturated monomer (c) for the acrylic modified epoxy ester resin is preferably in a range of 0.6-2/1/0.3-1.7. The method for preventing the contamination is effected by using the aqueous coating composition. The coated article is produced by using the method.
