Anti-fouling paint containing a copolymer of a triorganotin salt of an unsaturated carboxylic acid

摘要

An anti-fouling paint for ships' hulls comprises an aqueous emulsion of a film-forming emulsion copolymer and a substantially water-insoluble metalliferous pigment capable of reacting with seawater to form a water-soluble metal compound. The compound contains units of at least one triorganotin salt of an olefinically unsaturated carboxylic acid and units of at least one olefinically unsaturated comonomer selected so that the copolymer has a glass transition temperature of less than 30 DEG C.
