Golf ball

摘要

An object of the present invention is to provide a golf ball having high resilience. The present invention provides a golf ball having a constituting member, wherein at least a part of the constituting member is formed from a rubber composition containing (a) a base rubber, (b) a co-crosslinking agent, (c) a crosslinking initiator, and (d) an organic sulfur compound, the organic sulfur compound being derivatives of thiophenols and disulfide with a strong electron withdrawing substituent.

1. A golf ball having a constituting member, wherein at least a part of the constituting member is formed from a rubber composition containing (a) a base rubber, (b) a co-crosslinking agent, (c) a crosslinking initiator, and (d) an organic sulfur compound including at least one represented by following formulae (1) to (3); in formula (1), R1 to R5 each independently represent COOR11 or H, and at least one of R1 to R5 is COOR11, and COOR11 is COOX, COOCOX, or COOCOR12, wherein X is any one of Br, Cl, or F and R12 is an alkyl group having a carbon number of 1 to 17 where one or more hydrogens of the alkyl group are optionally substituted; in formula (2), R1 to R10 each independently represent COOR11 or H, and at least one of R1 to R5 and at least one of R6 to R10 are COOR11, and COOR11 is COOX, COOCOX, or COOCOR12, wherein X is any one of Br, Cl, or F and R12 is an alkyl group having a carbon number of 1 to 17 where one or more hydrogens of the alkyl group are optionally substituted; in formula (3), R1 to R5 each independently represent COOR11 or H, and at least one of R1 to R5 is COOR11, and COOR11 is COOX, COOCOX, or COOCOR12, wherein X is any one of Br, Cl, or F and R12 is an alkyl group having a carbon number of 1 to 17 where one or more hydrogens of the alkyl group are optionally substituted; n is a natural number equal to or larger than 1, and M represents a metal atom having a valence equal to or larger than 1.
