FIELD: chemistry.
SUBSTANCE: invention relates to an antifouling coating composition and can be used to protect ships, fishing nets and other underwater structures or equipment which can be attacked by aquatic organisms, such as molluscs, mussels, sea algae etc. The composition contains a zinc derivative of an ester functional polymer and copper pyrithione in the form of particles, wherein the particles have an average aspect ratio in the range of about 8 to about 15. The zinc derivative of the ester functional polymer and copper pyrithione are obtained by reacting an acid functional polymer with zinc pyrithione and a copper salt or copper carboxylate. Also disclosed is an antifouling coating containing said composition.
EFFECT: invention improves the effectiveness of the antifouling coating composition.
