Patent ID: 7999019

Claim:
A golf ball which comprises a core and a cover, the base polymer of the cover comprising a thermoplastic polyurethane elastomer, and the cover comprising 0.1 parts by weight or more and 10 parts by weight or less of a hindered amine heat and light resistance stabilizer having two or more hindered phenol groups, per 100 parts by weight of the base polymer, an ultraviolet ray absorbing agent, a heat resistance stabilizer, and titanium oxide; and provided that if the molar concentration of the hindered amine heat and light resistance stabilizer is defined as A; the molar concentration of the ultraviolet ray absorbing agent is defined as B; and the molar concentration of the heat resistance stabilizer is defined as C, the molar ratio (A/B) is 0.01 or greater and 2.5 or less, while the molar ratio [(A+C)/B] is 0.01 or greater and 2.5 or less, and wherein the cover has shore D hardness of 40 or greater and 55 or less.
