[PROBLEMS] A water-based resin composition whose dry coating film has excellent adhesion, adhesion, rust prevention to metal surfaces, and stability to metals, ceramics, olefins, and more specifically, adhesion to olefinic materials. Providing a water-based resin composition having excellent properties and adhesiveness. (A) a copolymer of an olefin and an α, β-ethylenically unsaturated carboxylic acid, (B) a resin having 5% by mass or more of a structural unit derived from maleic acid in its structure, and (C) a rosin And / or a water-based resin composition containing three components of a rosin derivative as essential components. |
