Abstract
Abstract Underwater anti-fouling coating composition which contains a high molecular organic tin compound as an anti-fouling component and also as a film forming component, in which said high molecular organic tim compound is prepared by reacting an alkyd resin having free carboxyl groups and having a resin acid value of larger than 20 with organic tin oxide in an amount less than equivalent to said free carboxyl groups of said alkyd resin, thereby obtaining an underwater anti-fouling coating composition with superior anti-fouling effect and neither unpleasant odor nor irritating property, and further with good adhesiveness to the articles to be coated.
