Abstract
An antifouling paint containing a copolymer including a recurring unit of the formula: ##STR1## wherein R.sup.1 is hydrogen atom, methyl or an alkoxycarbonyl, R.sup.2 is hydrogen atom or an alkoxycarbonyl, A is an acid ion-terminated pendant group, M is a transitional metal ion, L is a monobasic organic acid ion, and m is the valency of the transitional metal M; and an amount of an organic ligand capable of coordinating to the transitional metal. The ion-association and reactivity of the metal in the copolymer may be retarded by complexing with the organic ligand in situ.
