A phenyl napthol derivative according to the present invention is expressed by general formula (1). In the formula: R1-R3 are a hydrogen atom, an alkyl group, or an aryl group; R2 and R3 may be bonded together to form an aliphatic hydrocarbon ring or a hetero ring; a and b are each an integer of 0-4; and R4 and R5 are a hydroxyl group, an alkyl group, a haloalkyl group, a cycloalkyl group, an alkoxy group, an amino group, a hetero-ring group that contains a nitrogen atom as a hetero atom and bonds via the nitrogen atom, a cyano group, a nitro group, a formyl group, a hydroxycarbonyl group, an alkyl carbonyl group, an alkyoxycarbonyl group, a halogen atom, an aralkyl group, an aralkoxy group, an aryloxy group, an aryl group, a heteroaryl group that bonds via an endocyclic carbon atom, an alkylthio group, a cycloalkylthio group, an arylthio group, or a hetero arylthio group. |
