摘要：
A polyester resin for an antifouling paint which contains a structural unit of the formula (I) wherein R1 is H or alkyl having 1 to 3 carbon atoms, R2 is H or methyl and n is an integer of 0-4, in a proportion of not less than 90 mol % and a metal in the main chain at a concentration of 10-300 eq/106 g, and which has an acid value of 20-1000 eq/106 g. A combined use of the polyester resin with a natural antifouling agent affords a paint with extremely less burden on the marine environment.
