Claim:
An amino group containing phenol derivative represented by a general formula (1) show below: (wherein, R 1 , R 2 and R 3 , which may be identical or different, each represent an alkyl group of 1 to 9 carbon atoms, an alkoxy group of 1 to 10 carbon atoms, a COOR group (in which R represents an alkyl group of 1 to 6 carbon atoms) or a hydrogen atom; R 4 and R 5 , which may be identical or different, each represent an alkyl group of 1 to 9 carbon atoms or a hydrogen atom; X represents —O—, —S—, —SO 2 —, —C(CH 3 ) 2 —, —CH 2 —, —C(CH 3 )(C 2 H 5 )—, or —C(CF 3 ) 2 —; and n represents an integer of 1 or greater); provided that when n is 2 and X is —CH 2 —, the X group connecting the two phenol rings in the center of the compound is in the ortho orientation with respect to the OH group on both phenol rings.
