Anti-fouling top coat paints for application to ship's hulls, effctive in delaying the gross infestation of hulls for considerable periods, consist of a film-forming copolymer containing from more than 50 up to 80% by weight of at least one triorgano tin salt of an olefinically unsaturated carboxylic acid and a substantially water insoluble metalliferous pigment capable of reacting with seawater to form a water-soluble metal compound.
