This antifouling agent can be prepared and used in the form of e.g. coating material, solution, emulsion. In the case of coating material, the compound of formula I is compounded preferably at 50 wt. ppm to 0.5 wt.% in prepared coating materials. In the case of solution, the compound of formula I is compounded at 50 wt. ppm to 0.5 wt.% in a film-forming agent (e.g. natural resin, vinyl chloride resin) followed by dissolution in a solvent into a solution.
