PROBLEM TO BE SOLVED: To provide a water-based coating material having excellent aesthetics, moisture absorption and desorption, and the like. The aqueous coating material of the present invention is a synthetic resin emulsion (A), a moisture-absorbing / releasing powder (B), an average particle size of 0.4 μm or more and less than 80 μm, and a refractive index of 1.4 or more and 2.0 or less. The granular material (C) , the aggregate (D) having an average particle diameter of 80 μm or more, and the hydrophobic substance (E) having a solubility in water of 10 g / 100 g or less and a boiling point of 200 ° C. or more are contained in the above-mentioned powder or granular material (C). The weight ratio [(C) / (D)] with the aggregate (D) is 0.1 / 1 to 10/1. [Selection diagram] None |
