Patent ID: 8907020

Claim:
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), R 1 to R 5 each independently represent COOR 11 or H, and at least one of R 1 to R 5 is COOR 11 , and COOR 11 is COOX, COOCOX, or COOCOR 12 , wherein X is any one of Br, Cl, or F and R 12 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), R 1 to R 10 each independently represent COOR 11 or H, and at least one of R 1 to R 5 and at least one of R 6 to R 10 are COOR 11 , and COOR 11 is COOX, COOCOX, or COOCOR 12 , wherein X is any one of Br, Cl, or F and R 12 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), R 1 to R 5 each independently represent COOR 11 or H, and at least one of R 1 to R 5 is COOR 11 , and COOR 11 is COOX, COOCOX, or COOCOR 12 , wherein X is any one of Br, Cl, or F and R 12 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.
