Abstract: The present invention aims to develop an aqueous heat-shielding coating material to which low staining properties are imparted to suppress a reduction in heat-shielding properties due to the reduction in solar reflectance caused by adhesion of contaminants in the air during outdoor exposure, thereby maintaining the heat-shielding properties for a long period of time. The above problem is solved by providing a resin composition for an aqueous coating material including: (A1) a water-soluble and/or water-dispersible resin; (A2) a heat-shielding pigment; (B1) an organosilicate and/or a modified product of the organosilicate; and (B2) a curing catalyst that promotes a hydrolysis/condensation reaction of an alkoxysilyl group.
