PURPOSE:To provide the titled coating preventing aquatic organisms from attaching to underwater construction, fishnets, ship bottoms etc., comprising a copolymer from a specific silicon-contg. (meth)acrylate and (meth)acrylic and/or vinyl monomer (s) each free from silicon and an ultraviolet light absorb er. CONSTITUTION:The objective coating composition comprising (A) a copolymer from (i) a silicon-contg. (meth)acrylate of formula (R<1> is H or CH3; R<2>, R<3> and R<4> are each 1-18C alkyl, cycloalkyl or phenyl) and (ii) silicon atom-free organic monomers consisting of (meth) acrylic and/or vinyl compound (s) and (B) an ultraviolet light absorber. Preferably, one or more of the R<2>, R<3> and R<4> in the formula is (are) >=4C alkyl, cycloalkyl or phenyl.
