RUBBER COMPOSITION, TIRE, BISPHENYL DIAMINE COMPOUND AND ANTI-AGING AGENT

Provided is a rubber composition that has better weather resistance than conventional rubber compositions and can inhibit rubber article surface discoloration. The rubber composition contains at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one bisphenyldiamine compound represented by formula (I). In formula (I), R 1 , R 2 , R 5 , and R 6 each represent, independently of one another, a hydrogen atom, an alkyl group having a carbon number of 1-10, or a phenyl group, but R 1 and R 2 do not both simultaneously represent a hydrogen atom and R 5 and R 6 do not both simultaneously represent a hydrogen atom, R 3 and R 4 each represent, independently of one another, an alkyl group having a carbon number of 1-8 or an aralkyl group, A represents an alkylene group having a carbon number of 1-12, and l, m, and n each represent an integer of 0 or 1.
