INK FOR INK-JET PRINTING USE

摘要

PROBLEM TO BE SOLVED: To provide an ink for ink-jet printing use capable of forming images good in hue, exhibiting a sharp absorption with narrow half-width and good in color reproducibility on any image-receiving paper through preventing dye aggregation and bronze phenomenon on image-receiving paper. SOLUTION: This water-based ink (composition) for ink-jet printing use is characterized by that dye J-association particles 2-200 nm in average size and water-dispersible polymeric microparticles 10-400 nm in average size are contained at 1-10 wt. times the dye J-association.
