Patent ID: 8469835

Claim:
A golf ball having a core, an intermediate layer covering the core, and a cover covering the intermediate layer, wherein said intermediate layer comprises an ionomer resin and does not include a thermoplastic polyester elastomer, said cover comprises a thermoplastic polyurethane containing a polycarbonate polyol as a constitutional component, wherein the thermoplastic polyurethane is contained in an amount of 50 parts by mass or more in 100 parts by mass of a resin component of said cover, the polycarbonate polyol has, as a repeating constitutional unit, a repeating unit (A) shown in a following Formula (I), and a repeating unit (B) shown in a following Formula (II) and having a different structure from that of (A), and a molar ratio of (A)/(B) is from 30/70 to 70/30; wherein R 1 is a bivalent residue obtained by removing two hydroxyl groups from a diol having 4 carbon atoms; wherein R 2 is a bivalent residue obtained by removing two hydroxyl groups from a diol having 6 carbon atoms; wherein the thermoplastic polyurethane has hysteresis loss of 35% or less with respect to the energy applied at the elongation of 80%, when the elongation at break is 100% and the polyurethane cover has a slab hardness of from 20 to less than 30 in Shore D hardness.
