GOLF BALL |
| 摘要 |
The invention provides a golf ball having a core and a cover of one layer or a plurality of layers, the core being formed of a material molded under heat from a rubber composition containing: (A) a base rubber, (B) an organic peroxide, and (C) water and/or a metal monocarboxylate. The core has a hardness profile which satisfies specific relationships between the JIS-C hardness at the core center (Cc), the JIS-C hardness at a position 10 mm from the core center (C10) and the JIS-C hardness at the core surface (Cs). |

1. A golf ball comprising a core and a cover of one layer or a plurality of layers, wherein the core is formed of a material molded under heat from a rubber composition comprising the following components A to C:
(A) a base rubber, (B) an organic peroxide, and (C) water and/or a metal monocarboxylate, and has a hardness profile which, letting Cc be the JIS-C hardness at a center of the core, C10 be the JIS-C hardness at a position 10 mm from the core center and Cs be the JIS-C hardness at a surface of the core, satisfies the following conditions (1) to (3):
0≦C10−Cc≦10 (1)C10−Cc<Cs−C10 (2)20≦Cs−C10 (3)with the proviso that Cc is at least 50 and Cs is not more than 80. |
