Kind Code:
A1
Abstract:
Provided is an antifouling coating composition which maintains a stable coating film dissolution rate for a long period of time in a low-temperature sea area, and which is capable of maintaining a stable antifouling performance without the occurrence of a coating film abnormality such as a crack. The present invention provides an antifouling coating composition which contains a copolymer A, a polymer B and a plasticizer C, and which is configured such that: the copolymer A is a copolymer of a monomer (a) and an ethylenically unsaturated monomer (b) other than the monomer (a); the monomer (a) is represented by general formula (1); the content of the monomer (a) is 15-35% by mass relative to the total mass of the monomer (a) and the monomer (b); and the polymer B is a (meth)acrylic acid ester polymer other than the copolymer A, which has a weight average molecular weight of 20,000-100,000.
