AQUEOUS COATING COMPOSITION, AND ITS PRODUCTION

摘要

AQUEOUS COATING COMPOSITION, AND ITS PRODUCTION The invention provides 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 compound (IV) reactive with 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; 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 has good storage stability and can provide a coating film of good performance.
