Solid golf ball
First Claim
1. A solid golf ball comprising at least one core layer, and at least one cover layer formed on the at least one core layer, wherein said at least one core layer is formed by vulcanizing and press-molding a rubber composition comprising (a) a base rubber, (b) a co-crosslinking agent, (c) an organic peroxide, (d) a filler material, and (e) at least one organic sulfur compound selected from the group consisting of(i) a compound represented by the following Formula (1):
-
wherein R1 to R5 are independently a hydrogen or a substituent group, and at least one of R1 to R5 is a substituent group, (ii) a compound represented by the following Formula (2)
wherein R6 to R15 are independently a hydrogen or a substituent group, at least one of R6 to R10 and at least one of R11 to R15 are substituent groups, and n is an integer of not less than 1, and (iii) a compound represented by the following Formula (3)
wherein R16 to R25 are independently a hydrogen or a substituent group, at least one of R16 to R20 and at least one of R21 to R25 are substituent groups, and M represents a bivalent metal atom;
and wherein at least one structure represented by the following Formula (4) in the compounds represented by formula (1) to (3);
has a substituent constant of not less than 1.50 wherein R26 to R30 correspond to either R1 to R5 in Formula (1), R6 to R10 in Formula (2), R11 to R15 in Formula (2), R16 to R20 in Formula (3), or R21 to R25 in Formula (3).
