PROBLEM TO BE SOLVED: To provide an aqueous coating composition that provides an organic-inorganic hybrid film having a high hardness and excellent wear resistance with an aqueous solvent, and also excellent in water resistance, and a method of coating the aqueous coating composition To provide. SOLUTION: A hydrophilic polymer (A) having an amino group, a hydrophilic polymer (B) having a hydroxyl group, a trivalent or higher silane compound (C), an unsaturated carboxylic acid (D) and water (E) are mixed. By using the aqueous coating composition, an organic-inorganic hybrid coating film having high hardness, excellent wear resistance, and excellent water resistance can be prepared by a relatively mild condition and a simple method.
