It is preferable that the phenol compound further has a brightness by Hunter of 75 or more. In general formula (I), R1 is hydroxyl or a halogen atom; p is 0 or an integer of 1 to 5; R2 and R3 are each independently a hydrogen atom or C1-6 alkyl; R4 is a hydrogen atom, C1-6 alkyl, optionally substituted phenyl, or optionally substituted benzyl; and each wavy line represents E- or Z-configuration or a mixture of both.
