<p>A novel azo compound represented by the following formula (1) wherein A represents the following formula (2) and is located preferably in a position meta or para to the azo group; R 1 and R 2 each independently represents hydrogen, carboxy, sulfo, nitro, C 1 -C 4 -alkoxy, etc; R 3 and R 4 each independently represents hydrogen, halogeno, cyano, carboxy, sulfo, nitro, C 1 -C 4 alkyl, hydroxy, or C 1 -C 4 alkoxy; and n is 0 or 1. In the formula (2), R 5 represents cyano, carboxy, C 1 -C 4 alkyl, C 1 -C 4 alkoxycarbonyl, or phenyl; and R 6 , R 7 , and R 8 , each independently represents hydrogen, halogeno, cyano, carboxy, sulfo, nitro, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, or acylamino. The compound is useful as a black dye, especially one for ink compositions for, e.g., ink-jet prints. Also provided are: an ink composition which contains the compound and has excellent storage stability; and a print obtained through recording with the ink. The print is excellent in light resistance, ozone resistance, fastness to moisture, etc.</p> |
