Disclosed is an aqueous coating composition which enables to simplify storage of an anti-staining agent. The aqueous coating composition is excellent in coating stability when the anti-staining agent is mixed with an emulsion resin coating material, and also excellent in anti- contamination properties. Specifically, the aqueous coating composition essentially contains a synthetic resin emulsion (A) having a pH of not less than 4.0 and not more than 10.0 and a neutral silica sol (B) having a particle diameter of 1-200 nm and a pH of not less than 5.0 and less than 8.5. The aqueous coating composition contains 0.1-50 parts by weight of the neutral silica sol (B) component per 100 parts by weight of the solid content of the synthetic resin emulsion (A) in terms of solid content.
