Provided is a resin composition for an aqueous antifouling paint that has excellent storage stability, water resistance in seawater, can exhibit an antifouling effect over a long period of time, and has excellent adhesion and self-polishing properties. To do. A resin composition for an aqueous antifouling paint comprising a polymer (A) containing a divalent metal dispersed in a dispersion medium composed of water or a water / organic solvent mixture, the polymer (A) A) Divalent metal-containing ethylenically unsaturated monomer unit (a1) 1 to 40% by mass Carboxyl group-containing ethylenically unsaturated monomer unit (a2) 0 to 8% by mass Hydroxyl group-containing ethylenically unsaturated monomer unit (a3) 0 to 40% by mass Other ethylenically unsaturated monomer units (a4) 99-22% by mass A resin composition for an aqueous antifouling paint comprising at least one polymer polymerized in two or more stages.
