<；P>；PROBLEM TO BE SOLVED: To provide an aqueous antifouling paint having antifouling properties comparable to an organic solvent-based antifouling paint. <；P>；SOLUTION: This aqueous antifouling paint comprises an alkenyl succinic anhydride, having an alkenyl group of &ge；16C, liquid at a room temperature, and a surfactant emulsifying the anhydride in water. The aqueous antifouling paint exerts such an antifouling effect comparable to the organic solvent-based antifouling paint as to prevent adhesion of aquatic organisms for long periods by virtue of containing the alkenyl succinic anhydride. The aqueous antifouling paint has good workability in handling and enables to control a load to environment because it contains no or little organic solvent. <；P>；COPYRIGHT: (C)2008,JPO&INPIT
