PROBLEM TO BE SOLVED: To provide a water-based resin composition a dried film of which is excellent in tightness and adhesiveness to metals, ceramics, olefins and the like, rust prevention on metal surfaces and stability; more concretely, the water-based resin composition excellent in tightness and adhesiveness with olefin-based materials. SOLUTION: The water-based resin composition comprises 3 components which are (A) a copolymer of an olefin withα,β-ethylenically unsaturated carboxylic acid, (B) a resin containing≥5 mass% structural unit derived from maleic acid in the structure and (C) rosin and/or a rosin derivative as essential components.
