Disclosed is an azo compound represented by the formula (1) below, a salt thereof, or a copper complex salt compound thereof. (In the formula, R1 and R2 independently represent a hydrogen atom, a sulfonic acid group, a lower alkyl group or a lower alkoxyl group; R3-R6 independently represent a hydrogen atom, a lower alkyl group or a lower alkoxyl group; R7 represents a lower alkyl group or a lower alkoxyl group; and n represents 0 or 1.)
