Dye ink composition, cyan dye ink, dye ink for inkjet printing, inkjet printing method, and dye aqueous solution |
| abstract |
The present invention provides a dye ink composition including a compound A to a compound D which are phthalocyanine dyes having specific substituents at β positions and water, a dye ink for ink jet recording, the dye ink including the dye ink composition, an ink jet recording method, and an aqueous dye solution. There are thereby provided a dye ink composition that enables the formation of an image having high printing density on both ink jet paper and plain paper, that enables stable ejection of an ink even during long time use, and that enables the formation of an image having high printing density and has good continuous ejection stability even after a long period of time has passed after preparation; a cyan dye ink including the dye ink composition; a dye ink for ink jet recording, the dye ink including the dye ink composition; an ink jet recording method using the dye ink for ink jet recording; and an aqueous dye solution that can be used to produce the dye ink composition. |
