The present invention relates to an azo compound represented by the following formula (1): (wherein, in the formula (1), R<SUB>1 </SUB>represents a hydrogen atom; a hydroxyl group; a carboxyl group; a (C<SUB>1</SUB>-C<SUB>4</SUB>)alkyl group which may be substituted by a hydroxyl group or a (C<SUB>1</SUB>-C<SUB>4</SUB>)alkoxy group; or the like, and A represents an aliphatic amine residue having a carboxyl group or a sulfo group, respectively;) or a salt thereof; an ink composition containing the same; and an inkjet recording method and a colored object using the same. Said azo compound has a high color value and has a hue between yellow and red or a brown hue. The ink containing said azo compound has satisfactory storage stability, and exhibits, when printed therewith, a stable ejection property even on a thermal type inkjet printer, and gives a print of high quality (superior in light fastness, ozone gas fastness and moisture fastness).
