Abstract: Provided is a rubber composition that contains at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one bisanilino compound represented by formula (I). In formula (I), R1 and R2 each represent, independently of one another, a hydrogen atom or an alkyl group having a carbon number of 1-6, m and n each represent an integer of 0 or 1, A1 represents an alkylene group having a carbon number of 1-7, A2 represents an alkylene group having a carbon number of 1-8, X1 represents an oxygen atom, a sulfur atom, or an —NR3— group, and X2 represents an oxygen atom, a sulfur atom, or an —NR4— group, where R3 and R4 each represent a hydrogen atom or an alkyl group having a carbon number of 1-4, or collectively form an alkylene group having a carbon number of 1-4.

Abstract: 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), R1, R2, R5, and R6 each represent, independently of one another, a hydrogen atom, an alkyl group having a carbon number of 1-10, or a phenyl group, but R1 and R2 do not both simultaneously represent a hydrogen atom and R5 and R6 do not both simultaneously represent a hydrogen atom, R3 and R4 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.

Abstract: Provided is a rubber composition that has better weather resistance than conventional rubber compositions and can inhibit surface discoloration of a rubber article. The rubber composition contains at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one amine compound represented by formula (I) shown below. In formula (I), R1 and R2 each represent, independently of one another, an alkyl group having a carbon number of 1-10, an aralkyl group, or a phenyl group, and A represents an alkylene group having a carbon number of 6-30 that may include an interposed phenylene group.
