         R a  and R b  respectively independently indicate substitutable C 1  to C 30  organic groups, 
         Z a  and Z b  respectively independently indicate chemical single bonds or —SO 2 —, 
         X 1  and X 2  respectively independently indicate hydrogen atoms, halogen atoms, substitutable C 1  to C 10  alkyl groups, cyano groups, nitro groups, —OR 1 , —O—C(═O)—R 1 , —C(═O)—OR 1 , —O—C(═O)—OR 1 , —NR 2 (R 3 ), —NR 2 —C(═O)—OR 1 , —C(═O)—NR 2 (R 3 ), or —O—C(═O)—NR 2 (R 3 ), here, R 1 , R 2 , and R 3  respectively independently indicate hydrogen atoms or substitutable to C 20  organic groups, 
         n and m respectively independently indicate integers of 0 to 2, where either of n and m is not 0, and 
         when n and/or m is 2, two of R a  and two of R b  may be the same as each other or may be different. 
       
     
     
         2 . The antiaging agent as set forth in  claim 1 , wherein in said formula (I), R a  and R b  respectively independently indicate substitutable linear or branched C 1  to C 20  alkyl groups or substitutable phenyl groups.

         4 . A composition which contains (a) an organic material and (b) the antiaging agent as set forth in  claim 1 . 
     
     
         5 . A composition which contains (a) an organic material and (b) the antiaging agent as set forth in  claim 2 . 
     
     
         6 . A composition which contains (a) an organic material and (b) the antiaging agent as set forth in  claim 3 . 
     
     
         7 . The composition as set forth in  claim 4 , wherein said ingredient (a) is a synthetic polymer. 
     
     
         8 . The composition as set forth in  claim 4 , wherein said ingredient (a) is a synthetic rubber. 
     
     
         9 . The composition as set forth in  claim 4 , wherein said ingredient (a) is acrylic rubber or hydrogenated nitrile rubber.
