摘要:
Provided is a water soluble azo compound represented by the following formula (1) or a salt thereof, which serves as a yellow coloring matter having a hue with high brilliance which is suitable for ink jet recording, and which enables a recorded matter to have various superior fastness properties. When an ink composition is prepared using the azo compound or a salt thereof, the ink composition can have superior storage stability. Also provided is an ink composition containing the water soluble azo compound or a salt thereof. In the formula (1), R1 and R2 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or an alkoxy group having 1 to 4 carbon atoms; m represents an integer of 1 to 3; and A represents an amine residue represented by any one of the following formulae (2) to (5). In the formula (2), x represents an integer of 1 to 3. In the formula (3), y represents an integer of 1 to 11.
