Patent ID: 8859732

Claim:
A benzylic compound represented by formula (I): wherein Y is a hydroxyl group or an —NHR group; R is a hydrogen atom, an alkyl group or an aralkyl group; each R b is independently an alkoxy group having a carbon number of 1 to 6, a halogen atom, or an alkyl group having a carbon number of 1 to 6, which is optionally substituted by one or more halogen atoms; n is an integer of 0-4; and R a is represented by formula (b), (c) or (d): wherein * indicates the position of a bond; m 2 is 1 or 2; n 1 and n 3 are each independently an integer of 0-2; n 2 and n 4 are each independently an integer of 0-2, except that n 2 and n 4 are not both 0; each X 2 , X 2 ′ in the number of m 2 and X 2 ″ are independently a single bond, —O—, —S—, —COO—, —OCONH—, —NHCO— or —CONH—; each R 4 and each R 6 are independently a hydrogen atom, a methyl group or an aliphatic hydrocarbon group having a carbon number of not less than 5; R 5 is an aliphatic hydrocarbon group having a carbon number of not less than 5; m 3 is an integer of 0-15; n 5 is an integer of 0-11; n 6 is an integer of 0-5; each X 3 is independently a single bond, —O—, —S—, —COO—, —OCONH—, —NHCO— or —CONH—; each R 7 is independently a hydrogen atom, a methyl group or an aliphatic hydrocarbon group having a carbon number of not less than 5; each X 4 is independently a single bond, —O—, —S—, —COO—, —OCONH—, —NHCO— or —CONH; R 8 is a divalent aliphatic hydrocarbon group; each R 9 is independently an alkyl group having a carbon number of 14-30; n 7 is an integer of 1-5; and Ar is an arylene group.
