[Problem] To provide the following: an antifouling-paint composition and antifouling paint that do not produce coating defects and maintain excellent antifouling performance for a long period of time even when stationary; and a metal-atom-containing copolymer used in said antifouling-paint composition and antifouling paint. [Solution] A metal-containing copolymer that has at least one structure selected from among structures represented by general formula (1) and structures represented by general formula (2). In formula (1), M represents a divalent metal, R1 represents a C2 or C3 hydrocarbon, and n represents an integer from 1 to 20. In formula (2), M represents a divalent metal, R2 through R5 represent hydrocarbons, and m represents 0 or 1. Also, an antifouling-paint composition containing the aforementioned metal-containing copolymer. General formula (1): -COO-(R1-COO)n-M- General formula (2): -COO-(R2-OCO-R3-COO)m-M-OCO-R4-COO-R5-OCO- |
