(57) Summary: Composition A new class of marine coating compositions is disclosed which can be prepared without organotin and give self-polishing antifouling coatings. It is (i) one or more rosin-based components, preferably a first component selected from rosin or its copper or zinc derivatives, (ii) a monomer A which is a cyclic tertiary amide or imide bearing an alkenyl group, Acrylate comonomer B, and comonomer C selected from C1-C8 alkyl methacrylate and / or styrene; (iii) at least one slightly soluble metal-containing pigment; (iv) at least one pigment, which is identical to the pigment. A marine biocide, and optionally another highly insoluble pigment. [Effect] It is possible to form a film having high antifouling property without using an organic tin compound. |
