A coating composition comprising a rosin compound, a polymer containing organosilyl ester groups, and an antifoulant as essential components is disclosed. This rosin-based coating composition gives a coating film which forms no residue layer on the surface thereof over long-term immersion, is hence free from physical defects such as cracks and peeling and capable of maintaining a sufficiently high rate of film erosion and preventing the attachment of marine organisms over a long period of time has satisfactory suitability for recoating, and has the satisfactory ability to prevent marine-organism attachment over the out-fitting period.

Coating composition

A hydrolyzable self-polishing coating composition for use in preventing attachment of organisms to the surface of structures submerged in seawater, which comprises an anifoulant and a copolymer of an organosilyl group-containing monomer and a hemiacetal ester group-containing monomer.

A pigment dispersing agent for paints is a combination of particular amine compound and particular acrylic copolymer or a combination of particular amine compound, particular acrylic copolymer and particular polyester resin. This pigment dispersing agent is applicable to both acrylic resin series paints and polyester resin series paints.
