Abstract: A golf ball paint composition includes primarily a urethane paint made of a polyol and a polyisocyanate. The polyol is an acrylic polyol, and the composition has an elastic work recovery of at least 70%. The paint composition has a high self-repairing ability and is of high quality as a golf ball paint. Golf balls coated with this composition are able to maintain a good durability, in addition to which they have an excellent abrasion resistance and an excellent ball appearance.

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.

Abstract: An aqueous emulsion which comprises as a resin component a self-emulsifiable copolymer in which at least one ethylenically unsaturated monomer and at least one urethane prepolymer having at least one mercapto group and at least one hydrophilic, polar group are bonded by radical polymerization or in which at least one ethylenically unsaturated monomer, at least one organic polyisocyanate, at least one compound having at least one mercapto group and at least one active hydrogen-containing group and at least one compound having at least one hydrophilic, polar group and at least one active hydrogen-containing group are bonded by urethanization reaction and radical polymerization. The aqueous emulsion is better in storage stability than conventional ones.
