RESIN COMPOSITION FOR ANTI-FOULING COATING MATERIAL, ANTI-FOULING COATING MATERIAL, AND ANTI-FOULING FILM

摘要

Disclosed is a composition that includes: a vinyl-based polymer (A) that has an acid value of equal to or greater than 35mgKOH/g and includes a unit having a carboxyl group that forms ionic bonds with a divalent metal; and a vinyl-based polymer (B) that has an acid value of less than 20mgKOH/g and has a glass transition temperature (TgB) of equal to or less than 28°C. The composition exhibits favorable water resistance and sustains a superior undersea anti-fouling effect over a long period of time, without exhibiting a deterioration in self-polishing properties. Also disclosed is an anti-fouling coating material that includes the composition, and a film obtained from said coating material.
