Abstract
Aqueous coating composition comprising water insoluble resinous powder, aqueous resin, pigment and other optional additives including hardener, characterized by the fact that said water insoluble resinous powder is composed of a polymer obtained by reacting a mixture of epoxy resin and a resin having epoxy reactive functional groups, or a resin having both epoxy groups and epoxy reactive functional groups, with an amine in an amount sufficient to cause ring-opening of 10 to 50% of the total epoxy groups, or composed of carboxyl bearing resin admixed and reacted with high boiling basic compound. These compositions are excellent in storage stability, application characteristics and film performance.
