Problems solved by technology

If these aquatic organisms multiply on the surface of the substrate, for example, in the case of a ship, the surface roughness of the ship increases, the speed decreases and the fuel cost increases, or, for example, the substrate has an anti-corrosion coating film In the case of the base material, the damage of the anti-corrosion coating film may occur, the strength and function of the base material may be reduced, and the life of the base material may be significantly shortened.

The antifouling coating composition contains a hydrolyzable polymer (A) including at least one selected from the group consisting of polymers (A1) having structural units represented by formula (1) and polymers (A2) having structural units represented by formula (2), a tertiary carboxylic acid component (B) including versatic acid, and an antifouling component (C). In formula (1), M indicates zinc or copper, R1 independently indicate a hydrogen atom or methyl group. -COO-M-O-COR2 (2) In formula (2), M indicates zinc or copper, R2 indicates an organic group.

Description

technical field [0001] The present invention relates to an antifouling coating composition, an antifouling coating film, a substrate having an antifouling coating film, an antifouling substrate, a method for producing a substrate having an antifouling coating film, and an antifouling method for a substrate. Background technique [0002] Among substrates of ships, underwater structures, and fishing gear such as fishing nets, the surfaces of substrates exposed to water for a long time tend to adhere to animals such as oysters, mussels, and barnacles, plants such as seaweed, and various aquatic organisms such as bacteria. If these aquatic organisms multiply on the surface of the substrate, for example, in the case of a ship, the surface roughness of the ship increases, the speed decreases and the fuel cost increases, or, for example, the substrate has an anti-corrosion coating film In the case of a base material, the corrosion-resistant coating film may be damaged, the strength...
