ABSTRACT:
An antifouling paint for ships' hulls, comprising a film-forming copolymer and a pigment component, has the property that a rough film of the paint becomes smoother in relatively moving seawater. The film-forming copolymer contains from more than 50 up to 80 percent by weight of units of at least one triorganotin salt of an olefinically unsaturated carboxylic acid, the balance of the copolymer being units of at least one olefinically unsaturated comonomer. The pigment component comprises a metalliferous pigment capable of reacting with seawater to form a water-soluble metal compound and a pigment which does not react with or dissolve in seawater.
