An anticorrosive coating composition is provided which is excellent in adhesion to a substrate and in anticorrosiveness, and which provides a coating film whose surfaces hardly have bubbles remaining thereon even when the coating composition is applied by using a brush or a roller. The anticorrosive coating composition includes an epoxy resin (a), a curing agent (b) and a poly-&#x3b1;-olefin (c) that includes a structural unit derived from an &#x3b1;-olefin having 6 or more carbon atoms.

Anticorrosive coating composition, anticorrosive coating film, and method for preventing corrosion of substrate

A novel cyclic carboxylic acid formed by the addition reaction of an unsaturated carboxylic acid with a conjugated diene compound and a metal salt thereof are disclosed. A compounding agent (A) for an antifouling paint comprising one or more substances selected from the novel cyclic carboxylic acid, a derivative of the cyclic carboxylic acid (except a metal salt), a metal salt of the cyclic carboxylic acid and a metal salt of a derivative of the cyclic carboxylic acid, and an antifouling paint composition comprising the compounding agent (A) and a copolymer (B) for a self-polishing type antifouling paint are also disclosed. The antifouling paint composition can form an antifouling coating film which is a small burden to the environment, is uniformly eroded at a given rate, is capable of maintaining excellent antifouling performance for a long period of time and is applicable to ships or the like used in the highly fouling sea area.
