摘要：
The invention pertains to an antifouling coating composition comprising a copper acrylate polymer, 2-(p-chlorophenyl)-3-cyano-4-bromo-5-trifluoromethyl pyrrole (tralopyril), and solvent, with the coating composition being substantially free of further biocidal compounds, wherein the copper acrylate polymer is present in an amount of 60-99 wt. % and the tralopyril is present in an amount of 0.1-30 wt. %, the weight percentages for copper acrylate polymer and tralopyril being calculated on the dry weight of the coating composition. In one embodiment, the coating composition comprises 30-70 wt % of solvent, the weight percentage of solvent being calculated on the wet weight of the coating composition. It has been found that the coating composition according to the invention combines a good antifouling performance against both weed and shell fouling, for at least 12 months, i.e. a yacht season, with a high gloss finish, and, when a suitable application method is used, a smooth and level surface.
