Beschreibung
Zusammenfassung:	An aqueous coating composition includes an aqueous polyurethane resin including a polyurethane resin having an acid group and a polyamine compound, a water-soluble polymer, and an inorganic layered mineral. The aqueous polyurethane resin is included at a solid content of 50-80 mass %, the water-soluble polymer is included at a solid content of 5-20 mass %, and the inorganic layered mineral is included at a solid content of 10-30 mass %, relative to a total solid content of the aqueous coating composition. The aqueous coating composition has a total solid concentration of not less than 5 mass % and a viscosity of not larger than 50 mPa-second at 23° C.
