Comprising a silyl ester copolymer block units (A) and block units (B), the silyl ester copolymer block units (A) is (a) a polymerizable unsaturated carboxylic acid silyl component unit, and (b) derived from an ester the constituent unit (a) polymerization of a non-enabled and an unsaturated monomer unit, the block units (B), the following formula (1) or (2) (poly) oxyalkylene block derived from a mercapto compound represented by the silyl ester copolymer, and (poly) oxyalkylene the antifouling paint is provided which includes a block silyl ester copolymer:; or; Wherein, R 1 is one or more hydrocarbon groups or ether having from 1 to 30 carbon atoms-containing hydrocarbon group denotes a - bond; R 2 having from 1 to 30 carbon atom divalent hydrocarbon group or a group represented by the formula -CH (R 3) - [R 3 denotes a group of the formula R 4 -OR 5, R 4 is having from 1 to 30 carbon atoms 2 represents a hydrocarbon group, and R 5 are 1 represents the group of represents a hydrocarbon group - having 1 to 30 carbon atoms; X is or It represents; n is an integer from 1 to 5; m is an integer from 1 to 100; l is an integer from 1 to 5; k is an integer from 0 to 100; a is an integer of 0 or 1; j is an integer from 1 to 50; In addition, i is the valence of R 1 ordination.; If according to the invention, is reduced cracking property, the peeling resistance is reduced by the superior adhesion also to be able to adjust as required the rate of hydrolysis, antifouling performance (antifouling activity), antifouling properties (in particular, contaminated this material can form an excellent antifouling coating film from the antifouling properties) and long-term antifouling properties in many environments.
