Abstract:
1. A rubber composition comprising: (A) 100 parts by weight of a diene-based rubber (B) 0.1 to 10 parts by weight of, as a vulcanization accelerator, an amine salt compound of a carboxylic acid group-containing disulfide having the formula (I): wherein R 1 , R 2 and R 3 independently represent hydrogen or a hetero atom containing C 1 to C 20 organic group, which may be substituted with a substitution group, and X is a hetero atom containing C 1 to C 20 organic group, which may be substituted with a substitution group, and (C) 0.1 to 10 parts by weight of, as a vulcanization agent, of a cyclic sulfide compound having the formula (V): wherein R is a substituted or unsubstituted C 2 -C 20 alkylene group, a substituted or unsubstituted C 2 -C 20 oxyalkylene group or an aromatic ring-containing alkylene group, x is an integer of 2-6 on average, and n is an integer of 1-30.
