Fouling of a ship's hull is inhibited by an amine of the formula ##STR1## where R.sup.1 is a monovalent hydrocarbon group derived from a diterpene and R.sup.2 and R.sup.3 are each independently hydrogen, an alkyl group having 1 to 18 carbon atoms or an aryl group having 6 to 12 carbon atoms. The amine acts as a paint binder and as a marine biocide. An antifouling coating composition may comprise a pigment with the said amine as binder. Alternatively an antifouling coating composition comprises as binder an acid-functional polymer whose acid groups are blocked by a monoamine group which forms an organic-solvent-soluble salt of the polymer.
一种由二萜衍生的单价碳氢基团R1组成的胺化合物,其
化学式为##STR1##其中R2和R3各自独立地为氢、具有1至18个碳原子的烷基团或具有6至12个碳原子的芳基团,可抑制船体的污垢形成。该胺化合物可作为涂料粘合剂和海洋
生物杀菌剂。一种防污涂层组合物可包含具有该胺化合物作为粘合剂的
颜料。另一种防污涂层组合物包括一种酸功能聚合物作为粘合剂,其酸基被单胺基阻断,形成聚合物的有机溶剂可溶盐。
