Abstract: An anthraquinone compound represented by formula (1): (where R1 and R4 represent —H, a C1-C12 alkyl group, a C1-C12 alkyl group, a halogen atom, —CO2R9, —OCOR9, —COR9, a cyano group, or —CF3, R2, R3, R5 and R6 represent —H, a C1-C4 alkyl group, a C1-C4 alkoxy group, a halogen atom, —CO2R9, —OCOR9, —COR9, a cyano group, or —CF3. R7 and R8 represent —H, a C1-C12 alkyl group, or a C1-C12 alkoxy group. R9 represents a C1-C12 alkyl group, or a substituent represented by formula (a) (where R10 represents —H, a C1-C8 alkyl group, or a C1-C8 alkoxy group) or formula (b) (where R11 represents —H or a C1-C8 alkyl group); however, at least one of R1 through R6 represents a halogen atom, —CO2R9, —COR9, a cyano group, or —CF3).
