ABSTRACT:
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.degree. C.
The paint has the remarkable property that relatively moving seawater smooths the surface of the paint.
