Patent ID: 8450425

Claim:
A golf ball comprising: a core and a cover covering the core, wherein the cover is formed from a cover composition that contains as a resin component, (a) a high melt viscosity ionomer resin having a melt viscosity (190° C.) ranging from 500 Pa·s to 100,000 Pa·s measured by a flow tester, and (b) a low melt viscosity ionomer resin having a melt viscosity (190° C.) ranging from 1 Pa·s to 10 Pa·s measured by a Brookfield viscometer and a melt flow rate (190° C. *2.16 kg) ranging from 100 g/10 min to 2,000 g/10 min, in a ratio of (a) the high melt viscosity ionomer resin/(b) the low melt viscosity ionomer resin being 55 mass % to 99 mass %/45 mass % to 1 mass %, wherein at least one of metal ions neutralizing carboxyl groups of (a) the high melt viscosity ionomer resin and/or (b) the low melt viscosity ionomer resin is a divalent metal ion and a content of the divalent metal ion per 100 g of the resin component is at least 0.020 mole, and wherein the cover composition has a melt flow rate (190° C. *2.16 kg) ranging from 10 g/10 min to 100 g/10 min.
