DESCRIZIONE
The present invention relates to an antifouling coating composition, an antifouling coating film, a substrate with an antifouling coating film, a antifouling substrate, a method for producing substrate with an antifouling coating film, and a method for preventing substrate from fouling. The antifouling coating composition includes a hydrolyzable polymer (A) including at least one selected from the group consisting of a polymer (A1) having a structural unit represented by the formula (1) below and a polymer (A2) having a structural unit represented by the formula (2) below, a tertiary carboxylic acid component (B) including versatic acid, and an antifouling agent component (C).
