(57) : The invention relates to a coating composition comprising a) seawater-hydrolyzable groups covalently linked to a L 3 / 4 -- polymer backbone, which seawater-hydrolyzable groups are capable of undergoing hydrolysis or ion-exchange when exposed to sea - ::::, water, rendering the polymer partially soluble or dispersible in seawater, and b) zwitterionic groups covalently linked to a polymer ei backbone wherein the polymer backbones to which the sea-water-hydrolyzable groups and the zwitterionic groups are attached serve ega ) as a film-forming binder in the coating composition, and wherein the molar ratio of the seawater-hydrolyzable groups a) to the zwit - terionic groups b) is 0.1 or higher. The invention also relates to a method of providing a substrate with anti-fouling performance and 5.- to a coated substrate.
