Kind Code:
A1
Abstract:
Provided is a nonaqueous ink composition which contains a diketopyrrolopyrrole-based pigment and is nevertheless suitable for use as a nonaqueous ink composition to be ejected by an ink-jet method. The nonaqueous ink composition, which is to be ejected by an ink-jet method, comprises a pigment, a pigment dispersant, an organic solvent, and a resin, wherein the pigment includes a pigment A represented by formula (1) and the content of the pigment dispersant is lower than the content of the pigment.
