Abstract:
An aqueous polyurethane composition including a polyurethane resin and inorganic particles. The polyurethane resin comprises a product of reaction between a polyisocyanate ingredient comprising a polyisocyanate having a ring structure and a polyol ingredient comprising a macropolyol and an active-hydrogen-group-containing compound containing a hydrophilic group. With respect to the sum of the polyurethane resin and the inorganic particles, the amount of the contained polyurethane resin is 5-95 mass% and the amount of the contained inorganic particles is 5-95 mass%. The inorganic particles have an average particle diameter of 5-1,000 nm.
