Patent ID: 7101934

Claim:
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) one or more polyisocyanates, 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 more than 0.8 and less than 1.2, the component (B) comprises a mixture of at least one of elasticity-unmodified polyisocyanate and at least one of elasticity-modified polyisocyanate, the elasticity-modified polyisocyanate being modified with at least one of polyol selected from the group consisting of polyester polyols, polycarbonate polyols, polyolefin polyols, polyether polyols, animal and vegetable polyols and copolyols thereof, and the elasticity modified polyisocyanate is used in an amount of from 10 to 90% by weight based on the whole weight of the component (B), and the elasticity-modified polyisocyanate is modified in advance of curing the coating composition.
