摘要：
Azo compounds represented by formula (1) (In the formula, R1 represents a lower alkoxy group with a sulfone group. R2-R5 each independently represents a hydrogen atom, lower alkyl group or lower alkoxy group. X is an optionally substituted amino group, optionally substituted benzoylamino group, optionally substituted phenylamino group, optionally substituted phenyl azo group or optionally substituted naphthotriazole group. m represents 1 or 2 and n represents 0 or 1.) and salts thereof.
