ANTIFOULING COATING COMPOSITION, ANTIFOULING COATING FILM, SHIP OR SUBMARINE CONSTRUCT WHICH IS COATED WITH THE ANTIFOULING COATING FILM, AND ANTIFOULING METHOD FOR SHIP OUTER BOARD OR SUBMARINE CONSTRUCT

摘要

PROBLEM TO BE SOLVED: To provide an antifoulding coating film which is formed from the antifoulding coating composition and has a moderate coating film depletion rate from the initial stage of its submarine immersion and has excellent antifoulding properties over a long time period without anxiety of environment pollution, and a ship and submarine construct which is coated with the antifoulding coating film, and an antifoulding method for a ship outer board or a submarine construct surface using the antifoulding coating composition. SOLUTION: The antifouling coating composition comprises (a) a (meth)acrylic acid metal salt-based copolymer, which has a (meth) acrylic acid metal salt component unit and another component unit wherein, the metal is selected from Cu and Zn, and (b) a triphenylboron-amine complex of formula [I] or pyridine-triphenylboron and (f) an anhydrous gypsum as an inorganic dehydrating agent, wherein R1is a 3-30C alkyl group.
