Zusammenfassung:	To provide a coating composition, which is capable of providing a coating film on a resin part and on a steel plate part at the same time at lower temperatures than conventional coating compositions, and which is capable of providing a coating film that has excellent bending resistance. A clear coating composition, which is applied to a resin part and a steel plate part of an automobile body at the same time, and which contains a base material that contains an acrylic polyol, a crosslinking agent that is composed of an active methylene type blocked isocyanate and a melamine resin, and a curing catalyst. The mass ratio of the base material to the melamine resin is 1.5-9.0, and the mass percentage of the active methylene type blocked isocyanate in the composition is set within a specific range when the total of the mass percentage of the base material and the mass percentage of the melamine resin in the composition is taken as 100% by mass.
