ANTIFOULING COATING COMPOSITION, ANTIFOULING COATING FILM, ANTIFOULING SUBSTRATE, ROSIN COMPOUND FOR ANTIFOULING COATING COMPOSITION AND METHOD FOR PRODUCING ANTIFOULING COATING COMPOSITION

摘要

There is provided an antifouling coating composition capable of suppressing increase of viscosity as compared with a prior art, having long-term storage stability and exhibiting excellent antifouling property and water resistance (long-term mechanical properties) when forming a coating film, and to provide a relevant technology, including: a silylacrylic copolymer (A) having a component unit derived from triisopropylsilyl (meth) acrylate (A1) and a component unit derived from a polymerizable monomer (A2) having a polymerizable double bond; and a rosin compound (B) which is at least one of a rosin having an acid value of 180 (mg KOH / g) or less and a metal-free type rosin derivative having an acid value of 180 (mg KOH / g) or less, which are blended.
