PROBLEM TO BE SOLVED: To provide a coating composition which has good storage stability, can maintain stain resistance during outdoor exposure, and can form a coating film with good processability.SOLUTION: A coating composition comprises a hydroxy group-containing resin (a), a crosslinking agent (b), an anionic surfactant (c) containing a sulfonic group or a sulfonate group, and a nonionic surfactant (d) containing a polyoxyalkylene chain. The coating composition contains 1-20 pts.mass the anionic surfactant (c) containing a sulfonic group or a sulfonate group and 0.1-20 pts.mass the nonionic surfactant (d) containing a polyoxyalkylene chain with respect to 100 pts.mass of the total solids of the hydroxy group-containing resin (a) and the crosslinking agent (b). |
