| titleOfInvention | Ink composition, inkjet recording method and colored body |
| abstract | Provided is pigment for black ink and ink compositions thereof that are highly soluble in media having water as the main component, that are stable even when high concentration aqueous solutions are stored for long periods, that have high density in printed images, that do not produce bronzing in images wherein high concentration solutions have been printed, that have favorable color rendering, and that provide black recorded images, said images having excellent fastness. As the pigment for black ink, pigment (I) represented by formula (1) or salts thereof, and pigment (II) represented by formula (2) or a tautomer thereof, or salts thereof, are used. [In formula (1), Ra represents a C1-C4 alkyl group and X represents a sulfo-substituted aliphatic amino group.] [In formula (2), R1 represents a C1-C4 alkyl group, R2 represents a cyano group, R3 and R4 each independently represents a hydrogen atom or a sulfo group, the rings wherein R5 to R7 or R8 to R10 are substituted represent benzene rings when rings represented by dotted lines are absent and naphthalene rings when said rings are present, R5 to R7 each independently represents a hydrogen atom, a C1-C4 alkyl group, or a sulfo-substituted C1-C4 alkoxy group, R8 to R10 each independently represents a hydrogen atom, a C1-C4 alkyl group, or a sulfo-substituted C1-C4 alkylthio groups, and Group A represents a sulfo-substituted 2-naphthothiazolyl group.] |
