PURPOSE:To obtain an antifouling coating which is nontoxic and has a antifouling function, by incorporating a specified phosphorus nitride compound therein. CONSTITUTION:This antifouling coating is composed mainly of a halogenated phosphorus nitride compound of formula I and a coating resin. In formula I, n1 is an integer of 3 or more, at least part of three or more R1's and R2's are each a halogen atom as the essential component, and the remaining R1's and R2's are each -OR3, a group of formula II or -NH-(CH2)n2-COOR3 and may be the same as or different from each other; R3 is CmH2m+1; n2 is an integer of 1-5; m is an integer of 1-20. The amount of the halogenated phosphorus nitride compound to be incorporated is preferably 5-300pts.wt. based on 100pts. wt. coating resin.
