ABSTRACT:
An object of the present invention is to provide a coating composition used for a golf ball, which is superior in not only abrasion resistance and impact resistance but also weather resistance to a conventional coating used for a golf ball.According to the present invention, there is provided a coating composition used for a golf ball, which comprises (A) a polyester- and/or polyether-containing acrylic polyol having a hydroxyl value of from 30 to 180 mg KOH/g(solid) and (B) a polyisocyanate, wherein the component (A) is composed of a main chain comprising an acrylic polymer and a side chain comprising a polyester and/or a polyether, and a molar ratio of an isocyanate group in the component (B) to a hydroxyl group in the component (A), [NCO]/[OH], is from 0.5 to 1.5.
