  The present invention relates to an azo compound represented by the following formula (1) (wherein, each of R 1 and R 2 independently represents a hydrogen atom, a halogen atom, a cyano group, a carboxyl group, a sulfo group, a sulfamoyl group or the like, each of m and n independently represents 0 or 1, X represents a sulfo group, B represents a substituted p-phenylene group or a substituted p-naphthylene group (these may be substituted by a group selected from the group consisting of a sulfo group, a sulfo C1 to C4 alkoxy group, a C1 to C4 alkyl group and the like), and C represents a substituted phenyl group or a naphthyl group) or a salt thereof, an ink composition containing it, especially a black ink composition. Said pentakis-azo compound is excellent in solubility to medium whose main component is water and suitable for an water-soluble composition (ink composition and the like) for inkjet recording and writing tools; recorded articles recorded using said composition are excellent in fastnesses such as light fastness and ozone gas fastness; bronzing is not generated on the recorded images; and its recording liquids are good in storage stability.
