An aqueous coating composition which comprises a carboxy group-containing resin powder (I), a basic compound (II) and an aqueous resin (III), optionally with a reactive compound (IV) to at least one of the resin powder (I) and the aqueous resin (III), in an aqueous medium, the basic compound (II) being contained in an amount of 0.4 to 1.2 equivalents to the carboxy group in the resin powder (I) so as to disperse the resin powder (I) into the aqueous medium and the weight proportion of the resin powder (I) and the aqueous resin (III) being from 2:98 to 98:2. The coating composition thus obtained is excellent in storage stability and workability and can provide a coating film having good performances. |
