TRIPHENYLBORON COMPOUND-CONTAINING ANTIFOULING COATING COMPOSITION HAVING IMPROVED STABILITY, ANTIFOULING AGENT SET USED THEREFOR, AND METHOD FOR SUPPRESSING/CONTROLLING DECOMPOSITION OF TRIPHENYLBORON COMPOUND

摘要

An object of the present invention is to provide an antifouling coating material composition in which, though containing a triphenylboron compound as an antifouling agent, the triphenylboron compound is inhibited from being decomposed in production and long term storage and which is excellent in a storage stability and a static antifouling property of an antifouling coating film obtained therefrom. The antifouling coating material composition of the present invention comprises at least (A) a coating film-forming resin and (B) a triphenylboron-amine complex (b1) as an antifouling agent, and it further comprises (C) an amine compound other than the triphenylboron-amine complex (b1) described above as a decomposition inhibitor for the above compound (b1). A content of the amine compound (C) described above is preferably a proportion of 1.0 to 210 parts by weight per 100 parts by weight of the component (b1).
