Abstract: The invention provides an ink composition for ink-jet printing which does not cause clogging of nozzles of an ink-jet printer during printing, to thereby provide a print of desired printing quality; which ensures an appropriate drying rate of printed images; and which attains excellent color development. The ink composition for ink-jet printing, containing a pigment, a binder resin, a pigment dispersant, and a solvent, wherein the solvent is formed of (1) at least one glycol ether and at least one of a lactone compound and 2-pyrrolidone, or (2) at least one glycol ether acetate and at least one of cyclohexane and isophorone.

Abstract: Disclosed is a nonaqueous inkjet ink composition having excellent ink ejection stability, which does not clog a nozzle of a printer head portion when used for printing by an inkjet printer, thereby enabling achievement of a printed matter having excellent print quality. The nonaqueous inkjet ink composition is characterized by containing a pigment, a resin, a pigment dispersing agent, an organic solvent, and additionally a rust inhibitor.

Abstract: A nonaqueous inkjet ink composition that at printing by an inkjet printer, is free from clogging of a nozzle of printer head part and that excels in ink delivery stability leading to prints of excellent printing quality. The nonaqueous inkjet ink composition is one containing a pigment, a resin, a pigment dispersant, an organic solvent and an aminated alcohol, characterized in that the content of the aminated alcohol is in the range of 0.01 to 3 mass % based on the whole mass. The nonaqueous inkjet ink composition may be one characterized in that the water extract from the nonaqueous inkjet ink composition exhibits a pH value ranging from 6.0 to 10.0.
