[ What is claimed is:] [1.] An antifouling coating composition comprising(i) a biodegradable polymer (A) comprising at least one constituent unit (a) represented by the formula: [ STR 9 ] wherein n is zero or 1; X.sup.1 is an oxygen atom, a sulfur atom or --NH--; and R.sup.10 is a straight, branched
[ What is claimed is:] [1.] An antifouling coating composition comprising(i) a biodegradable polymer (A) comprising at least one constituent unit (a) represented by the formula: [ STR 9 ] wherein n is zero or 1; X.sup.1 is an oxygen atom, a sulfur atom or --NH--; and R.sup.10 is a straight, branched or cyclic alkyl group, an aryl group, a heterocyclic group, an aralkyl group or an acyl group, R.sup.10 being able to be substituted with an alkoxycarbonyl group, and at least one constituent unit (b) selected from the group consisting of formulae (I), (II) and (III): [ STR 10 ] wherein in the formula (I), R.sup.1 and R.sup.2 are independently a hydrogen atom, a chlorine atom, a bromine atom, a methyl group, an ethyl group or a phenyl group; in the formula (II), R.sup.3 and R.sup.4 are independently a hydrogen atom, a chlorine atom, a bromine atom, or a substituted or unsubstituted methyl or ethyl group; and in the formula (III), R.sup.5 and R.sup.6 are independently a hydrogen atom, a methyl group or an ethyl group, and R.sup.7 is a straight, branched or cyclic alkyl group, an aryl group, a heterocyclic group or an aralkyl group, which may have one or more substituents, and provided that when a constituent unit represented by formula (I) is a constituent unit of the polymer (A), in formula (IV) there is excluded the case where n is zero, X.sup.1 is an oxygen atom and R.sup.10 is an alkyl group having 1 or 2 carbon atoms or an acyl group having 1 to 5 carbon atoms, and(ii) an antifouling agent.
