Abstract
The present invention provides an antifouling coating composition, which can form an antifouling coating film capable of giving excellent slime resistance and has a property such that the recrystallization of an antifouling agent in a paint is depressed. The antifouling coating composition of the present invention is obtainable by blending a coating film forming resin (A) with as an antifouling agent, an inorganic copper antifouling agent (B) such as copper suboxide, etc and N,N′-dimethyl-N′-tolyl(N-fluorodichloromethylthio)sulfamide (C). The antifouling agent (B) is contained in an amount of preferably 60 to 1000 parts by weight based on 100 parts by weight of the coating film forming resin (A), and the antifouling agent (C) is contained in an amount of preferably 1.4 to 80 parts by weight based on 100 parts by weight of the coating film forming resin (A) and also the antifouling agent (C) is contained in an amount of preferably 0.1 to 100 parts by weight based on 100 parts by weight of the antifouling agent (B).
