PROBLEM TO BE SOLVED: To provide a compound while maintaining processability and a high moist heat resistant bonding property of a rubber composition obtained by blending the same with a rubber, suppressing bloom observed by blending with resorcin or an RF (resorcin-formaldehyde) resin as much as possible, having less bonding property reduction while storing the rubber composition and exhibiting a stable bonding property. SOLUTION: This compound is expressed by formula (1) [wherein, Rs are each independently a 1-8C aliphatic group, an alkoxy, hydroxy, carboxyl or amino which may be protected; Xs are each independently -CONH- or -COO-; (n) is an integer of 2 to 4; and (m) is an integer of 0 to 4, provided that (n+m) is 3 to 6].
