PROBLEM TO BE SOLVED: To provide a water paint composition which can be stored and maintained stably for a long period as a coating material and from which a coating film for efficiently adsorbing harmful air pollutant such as formaldehyde, ammonia or mercaptan contained in the air of indoor or outdoor through a long period can be formed and which is excellent in following capability to a ground. SOLUTION: The water paint composition contains a water-based resin dispersed body (A) containing a surfactant copolymerizable with an α,β-ethylenic unsaturated monomer and an ethylenic unsaturated monomer having carboxy group as essential ingredients in which 0.5-10 mass% of ethylenic unsaturated monomer having carbonyl group except the carboxy group is copolymerized, a compound (B) having two or more hydrazide groups in a molecule and activated carbon (C), wherein the average particle diameter measured by dynamic light scattering method is larger than the average pore diameter of the activated carbon.
