摘要:
Golf ball 2 has core 4, cover 6 and paint layer 12. The base polymer of the cover 6 includes a thermoplastic polyurethane elastomer. The cover 6 includes one or more kinds of ultraviolet ray absorbing agents. The paint layer 12 includes one or more kinds of ultraviolet ray absorbing agents. There are one or more kinds of ultraviolet ray absorbing agents (common ultraviolet ray absorbing agent) included in the cover 6 and the paint layer 12. The cover 6 includes the common ultraviolet ray absorbing agent in an amount of A parts by weight per 100 parts by weight of the base polymer, and the paint layer 12 includes the common ultraviolet ray absorbing agent in an amount of B parts by weight per 100 parts by weight of the resin component, with the ratio (A/B) being preferably 0.1 or greater and 10 or less. Preferably, the thermoplastic polyurethane elastomer is an MDI based polyurethane elastomer. The golf ball of the present invention is less likely to subject to color change, and excellent in the scuff resistance performance.
