<P>PROBLEM TO BE SOLVED: To provide a painted golf ball which is excellent in the gloss of a paint film, the even thickness of the paint film, and the adhesion of the paint film to a surface of a golf ball body. <P>SOLUTION: The method for producing the golf ball comprises applying a two-component curing type urethane-based aqueous paint including an aqueous polyol composition (A) and an aqueous polyisocyanate (B) to the golf ball body multiple times until the paint film has a desired thickness, such that an applied amount (mass after drying) of the paint per time is equal to 5 mg or more and equal to 80 mg or less. The aqueous polyol composition (A) contains an aqueous acrylic polyol (a-1), an aqueous urethane polyol (a-2), and an aqueous urethane resin (a-3) of a prescribed amount. A non-volatile content of the two-component curing type urethane-based aqueous paint ranges from 15 mass% to 60 mass%. <P>COPYRIGHT: (C)2010,JPO&INPIT |
