Abstract
A water-based paint composition includes a manganese oxide-based catalyst, activated carbon, at least one water-soluble resin selected from a group consisting of acrylic resin, modified acrylic resin, and fluorocarbon resin, a polyacrylate-based dispersant, and a water-based solvent. The water-based paint composition, although including the manganese oxide-based catalyst, allows a coating film to be resistant to chalking and weather.
