For ships, this increases the frictional resistance between the ship's hull and the seawater, reducing speed and increasing fuel consumption, resulting in large economic losses. For this reason, antifouling paints are applied to prevent the adhesion of marine organisms. A variety of antifouling paints are available as this type of antifouling paint.

However, these antifouling agents generally have a unique irritant property and many have an unpleasant odor, causing irritation to the skin, mucous membranes, etc. of the user. Therefore, unsaturated organotin compound monomers such as tributyltin acrylate and tributyltin methacrylate are used in advance as an antifouling agent that possesses the excellent performance of lower trialkyltin compounds as an antifouling agent and alleviates the physiological effects on the human body. Antifouling paints have been developed that contain as active ingredients polymers, copolymers of these monomers, or copolymers of unsaturated compounds containing these monomers and copolymers.

Therefore, when using a copper compound in combination with a copper compound to improve the antifouling performance of the antifouling paint disclosed in Japanese Patent Publication No. 40-21426, the copolymer of a copolymer of an unsaturated organotin compound disclosed in Japanese Patent Publication No. 40-21426, It has been discovered that the mixture with cuprous oxide has a drawback in that the viscosity increases significantly and gels during paint storage, resulting in poor stability and unusability as an antifouling paint. In addition, in recent years, antifouling paints have been known such as those described in JP-A-49-2788 and JP-A-51-7633-Sae.

The former contains a tricyclohexyltin-containing polymer as an active ingredient, and the latter contains a triphenylalkyltin-containing polymer as an active ingredient. However, all of these antifouling paints have the disadvantage that their viscosity significantly increases and gels during paint storage, resulting in poor stability. In order to improve this, the present inventor investigated various methods of synthesizing copolymers of unsaturated organotin compounds, and as a result, first synthesized an acrylic acid resin having a carboxyl group, and then converted the acrylic resin into a lower trialkyl resin. It has been discovered that an antifouling paint with good stability and antifouling performance can be obtained when the active ingredients are a polymeric organotin compound obtained by reacting with a tin compound and cuprous oxide. .
