    • PROBLEM TO BE SOLVED: To provide an aqueous antifouling coating resin composition having self-abrasiveness which excels in storage stability and the water resistance in seawater, can exhibit an antifouling effect over a long period, and furthermore excels in adhesion.
      SOLUTION: The aqueous antifouling coating resin composition is obtained by dispersing a polymer (A) containing a divalent metal in water or a dispersion medium comprising a water/organic solvent mixture and the polymer (A) is composed of 1-40 mass% divalent metal-containing ethylenically unsaturated monomer unit (a1), 0-8 mass% carboxyl group-containing ethylenically unsaturated monomer unit (a2), 0-40 mass% hydroxyl group-containing ethylenically unsaturated monomer unit (a3), 99-22 mass% other ethylenically unsaturated monomer units (a4) and comprises at least one polymer prepared by a two or more multi-stage solution polymerization.
