NONAQUEOUS INKJET INK COMPOSITION AND PRINTED MATTER OBTAINED USING SAME

摘要

A nonaqueous inkjet ink composition contains binder resin, pigment, pigment dispersant, and organic solvent. The organic solvent contains 40 to 80 percent by mass of the nonaqueous inkjet ink composition of diethylene glycol ethyl methyl ether and 7 to 50 percent by mass of the nonaqueous inkjet ink composition of propylene carbonate. Compositions that contain acetylene agent are excluded. The nonaqueous inkjet ink composition offers excellent wettability, fixing property, and discharge stability even when printed at high speed on targets whose printing surface is constituted by polyvinyl chloride, ethylene-vinyl acetate copolymer, or other vinyl polymer.
