Summary: | PROBLEM TO BE SOLVED: To provide an azo compound with excellent solubility and an oily or aqueous dye composition including the same.SOLUTION: There is provided an azo compound having a tetraethylammonium ion which is a metal complex salt of Cr or Co with two molecules of a monoazo compound represented by the formula (4) as a ligand as a counter ion. (4), where Ris a C1 to 4 alkyl group, Ris a C1 to 4 alkyl group, Rand Rare each independently H, a halogen atom, a nitro group, an aryl group, a C1 to 4 alkyl group, -SONHRor -COORand Ris H, a C1 to 8 monovalent aliphatic hydrocarbon group or the like.
