WATER-SOLUBLE BLACK COLORING MATTER

PROBLEM TO BE SOLVED: To provide a water-soluble black coloring matter excellent in light stability, water resistance and anti-SOX/NOX gas fastness, having large solubility, increased in adsorbability and suitable for ink for ink-jet printing. SOLUTION: The water-soluble azoviolanthrone coloring mat...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water-soluble black coloring matter excellent in light stability, water resistance and anti-SOX/NOX gas fastness, having large solubility, increased in adsorbability and suitable for ink for ink-jet printing. SOLUTION: The water-soluble azoviolanthrone coloring matter represented by formula (2) has many amide groups and sulfonic groups in coloring matter molecules, and is much improved in solubility and simultaneously increased in adsorbability of the coloring matter, and thereby the coloring matter is adsorbed on the paper surface in ink jet printing so that high color development is obtained. Simultaneously, water resisting property and anti-moisture fastness are much increased. COPYRIGHT: (C)2006,JPO&NCIPI
