Non-aqueous ink composition, ink set, recording method using same, method for producing recorded matter, recorded matter, and inkjet recording apparatus

Abstract

A nonaqueous ink composition contains a diketopyrrolopyrrole-based pigment and is suitable for use as a nonaqueous ink composition to be ejected by an ink-jet method. The nonaqueous ink composition includes 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. (In formula (1), X1 to X10 each independently represent a hydrogen atom, a halogen atom, an optionally branched C1-C5 alkyl group, an aromatic hydrocarbon group in which the hydrogen atoms may have been replaced, a cyano group, a nitro group, an amino group, —OH, —COOH, —COO−M+, —SO3H, —SO3−M+, a phthalimide group in which the hydrogen atoms may have been replaced, a phthalimidomethyl group, or a heterocyclic compound, and M+ represents a cation.)
