Abstract
A marine paint capable of becoming smoother in relatively moving sea water and having no or a low content of organotin comprises a film-forming acrylic polymer and a metalliferous pigment which is sparingly soluble in seawater. The acrylic polymer comprises 20-100 percent by weight of monomer units (A) selected from methyl acrylate and ethyl acrylate units, 0-45 percent by weight of monomer units (B) of a triorganotin salt of an olefinically unsaturated carboxylic acid and 0-80 percent by weight of monomer units (C) which are alkyl methacrylate units having 1-4 carbon atoms in the alkyl group or styrene units. Monomer units (A), (B) and (C) form at least 80 percent by weight of the acrylic polymer; the balance of the polymer if any comprises units of at least one other olefinically unsaturated comonomer.
