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 coating composition contains as essential components one or more antifoulants and copolymer obtained from monomers mixture comprising monomer A represented by formula (1): ##STR1## wherein R.sup.1 to R.sup.3 each is a group selected from alkyl groups and aryl groups and may be the same or different, and X is an acryloyloxy group, a methacryloyloxy group, a maleinoyloxy group, or a fumaroyloxy group and monomer B represented by formula (2):

Undersea antifouling treating composition

This invention is directed to an antifouling paint that contains a polymer having organosilyl groups and/or organosiloxane groups in side claims.

Antifouling paint

An antifouling paint is described, that contains as its essential components an antifoulant and a polymer of one or more of the monomers A represented by general formula (1) and/or copolymer composed of one or more of the monomers A and one or mroe vinyl polymerizable monomers B that are copolymerizable with said monomer A: ##STR1## wherein X is a hydrogen atom or a methyl group; n is an integer of 2 to 4; and m signifies the average degree of polymerization and is zero or a real number. The antifouling paint may contain a slipping agent as the third essential component to provide an even greater fouling resistance.
