The present invention provides a nonaqueous ink composition which is suitable for use as a nonaqueous ink composition to be ejected by means of an inkjet method even though at least one
pigment that is selected from the group consisting of a
perinone pigment, a diketopyrrolopyrrole
pigment and a halogenated
phthalocyanine pigment is contained therein. A nonaqueous ink composition to be ejected by means of an inkjet method, the nonaqueous ink composition containing a pigment, a pigment dispersant and an
organic solvent, wherein: the pigment contains at least one of a pigment A1 represented by formula (1-1), a pigment A2 represented by formula (1-2) and a halogenated
phthalocyanine pigment A3; and the pH values of the pigment A1 and the pigment A2 are within the range of 3 to 9. (In formula (1-1), each of X1 to X12 independently represents a
hydrogen atom, a
halogen atom, an optionally branched
alkyl group having 1 to 5 carbon atoms, an
aromatic hydrocarbon group in which
hydrogen atom may be replaced, a cyano group, a nitro group, an amino group, -OH, -COOH, -COO-M+, -SO3H, -SO3 -M+, a
phthalimide group which may be substituted by a
hydrogen atom, a
phthalimide methyl group, or a
heterocyclic compound; and M+ represents a cation.) (In formula (1-2), each of X1 to X10 independently represents a
hydrogen atom, a
halogen atom, an optionally branched
alkyl group having 1 to 5 carbon atoms, an
aromatic hydrocarbon group in which
hydrogen atom may be replaced, a cyano group, a nitro group, an amino group, -OH, -COOH, -COO-M+, -SO3H, -SO3 -M+, a
phthalimide group which may be substituted by a
hydrogen atom, a phthalimide
methyl group, or a
heterocyclic compound; and M+ represents a cation.)
