Abstract

Provided is an antifouling coating composition, which can form a coating film having good hardness and good physical properties and having a wear degree appropriate for expressing a long-term antifouling effect, has a viscosity not being excessively high, and makes it possible to reduce a content of volatile organic compounds, and a polymer-containing composition which is suitable for obtaining the antifouling coating composition. The polymer-containing composition contains a (meth)acryl-based copolymer (A-1), in which the (meth)acryl-based copolymer (A-1) contains a constitutional unit (U11) or a constitutional unit (U12) having carboxylate forming an ionic bond with a divalent metal atom, and has a weight-average molecular weight of 1,000 to 5,000, and the polymer-containing composition has a coating film hardness (Martens hardness) equal to or higher than 2.5 N/mm.
