摘要：
A multi-piece golf ball, comprising:
a solid inner core including a thermoplastic resin material, the solid inner core having a surface hardness within a range of 42 to 54 Shore D, wherein the solid inner core has a diameter within a range of 18 to 36 mm;
an outer core layer surrounding the solid inner core, the outer core layer including a polybutadiene rubber containing material, the outer core layer having a surface hardness within a range of 50 to 64 Shore D, wherein the outer core layer has a thickness within a range of 4 to 10 mm;
a mantle layer surrounding the outer core layer, the mantle layer including a thermoplastic polyurethane containing material, the mantle layer having a surface hardness within a range of 60 to 72 Shore D, wherein the mantle layer has a thickness within a range of 0.4 to 1.6 mm; and
a cover layer surrounding the mantle layer, the cover layer including a thermoplastic polyurethane containing material, the cover layer having a surface hardness within a range of 44 to 60 Shore D, the cover layer having a nominal thickness within a range of 0.6 to 1.6 mm,
wherein the Shore D surface hardness of the mantle layer is higher than the Shore D surface hardnesses of the solid inner core, the outer core layer, and the cover layer.
a solid inner core including a thermoplastic resin material, the solid inner core having a surface hardness within a range of 42 to 54 Shore D, wherein the solid inner core has a diameter within a range of 18 to 36 mm;
an outer core layer surrounding the solid inner core, the outer core layer including a polybutadiene rubber containing material, the outer core layer having a surface hardness within a range of 50 to 64 Shore D, wherein the outer core layer has a thickness within a range of 4 to 10 mm;
a mantle layer surrounding the outer core layer, the mantle layer including a thermoplastic polyurethane containing material, the mantle layer having a surface hardness within a range of 60 to 72 Shore D, wherein the mantle layer has a thickness within a range of 0.4 to 1.6 mm; and
a cover layer surrounding the mantle layer, the cover layer including a thermoplastic polyurethane containing material, the cover layer having a surface hardness within a range of 44 to 60 Shore D, the cover layer having a nominal thickness within a range of 0.6 to 1.6 mm,
wherein the Shore D surface hardness of the mantle layer is higher than the Shore D surface hardnesses of the solid inner core, the outer core layer, and the cover layer.
