AZO COMPOUND, INK COMPOSITION, AND COLORED OBJECT

摘要

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, C1-4 alkoxy, etc.; R<3> and R<4> each independently represents hydrogen, halogeno, cyano, carboxy, sulfo, nitro, C1-4 alkyl, hydroxy, or C1-4 alkoxy; and n is 0 or 1. [In the formula (2), R<5> represents cyano, carboxy, C1-4 alky, C1-4 alkoxycarbonyl, or phenyl; and R<6>, R<7>, and R<8> each independently represents hydrogen, halogeno, cyano, carboxy, sulfo, nitro, C1-4 alkyl, C1-4 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.
