Disclosed is an aqueous coating composition which is characterized in that it is obtained by mixing a hydrophilic cationic polymer (A) having an amino group, a nonionic polyalcohol (B), a tri- or more valent silane compound (C) and water (D). By using such an aqueous coating composition, an organic-inorganic hybrid coating film having high hardness and excellent wear resistance can be formed by a simple process under relatively mild conditions. |
