FISHING NET ANTIFOULING COATING COMPOSITION, COPOLYMER FOR FISHING NET ANTIFOULING COATING COMPOSITION, FISHING NET HAVING, ON SURFACE, ANTIFOULING FILM FORMED WITH THE COMPOSITION, FISHING NET IMPLEMENT AND UNDERWATER STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a fishing net antifouling coating composition which keeps an appropriate chemical release amount from the beginning of immersion in water, sustains an antifouling effect for a long period and exerts excellent antifouling performance against organisms adhered to fishing nets continuously for a long period.SOLUTION: A fishing net antifouling coating composition comprises a (meth)acrylic ester copolymer (A) obtained by copolymerization of 1-40 mass% of a (meth)acrylic ester monomer (a) of formula (1) with 60-99 mass% of an ethylenic unsaturated monomer (b) other than (a), a silicone oil (B) and an antifouling chemical (C). In formula (1), Ris H or a methyl group, and Ris a 10-22C alkyl group.
