Abstract
Abstract An antifouling paint is described, that contains as its essential components an antifoulant and a polymer of one or more of the monomers A represented by general formula (1) and/or copolymer composed of one or more of the monomers A and one or mroe vinyl polymerizable monomers B that are copolymerizable with said monomer A: ##STR1## wherein X is a hydrogen atom or a methyl group; n is an integer of 2 to 4; and m signifies the average degree of polymerization and is zero or a real number. The antifouling paint may contain a slipping agent as the third essential component to provide an even greater fouling resistance.
