ANTIFOULING COATING COMPOSITION, COATING FILM, AND COATING-FILM-ATTACHED BASE MATERIAL

WIPO Patent Application WO/2017/130864

A1

The present invention is an antifouling coating composition comprising (A) a silyl acrylic copolymer that has a constituent unit (a1) derived from triisopropylsilyl (meth)acrylate and a constituent unit (a2) derived from a polymerizable monomer having a polymerizable double bond, (B) a lower alcohol that has 1 to 3 carbon atoms, (C) an antifouling agent that contains a copper component and a zinc component and (D) a monocarboxylic acid compound, wherein the content of the lower alcohol (B) in the antifouling coating composition is 0.1 to 3% by mass. The present invention provides: an antifouling coating composition for forming a coating film which is dissipated in a reduced amount under a condition where the coating film is in contact with water at ambient temperature of about 25ºC as well as a condition where the coating film is in contact with water at a higher temperature of about 30ºC and which can maintain the physical properties thereof for a long period; a coating film produced by curing the antifouling coating composition; a coating-film-attached base material which comprises a base material and the above-mentioned coating film formed on the base material; and a method for producing the coating-film-attached base material.
