Ink composition, inkjet recording method, and colored material |
| abstract |
Disclosed is an aqueous black ink composition which enables the formation of an excellent black recorded image having extremely high ozone gas resistance and a neutral and achromatic color. The ink composition comprises: a dye (I) which comprises at least one compound represented by specific formula (1) or at least one tautomer or salt of the compound; a dye (II) which comprises at least one compound represented by specific formula (3) or at least one tautomer or salt of the compound; and a dye (III) which comprises at least one compound represented by specific formula (4) or at least one tautomer or salt of the compound. In formula (1), R 1 and R 2 independently represent a hydrogen atom, a sulfo group or the like; R 3 and R 4 independently represent a halogen atom, a sulfo group or the like; and n represents 0 or 1. In formula (3), m represents 0 or 1; R 101 to R 103 independently represent a hydrogen atom, a sulfo group or a C1-C4 alkoxy group; and a group D represents a phenyl or naphthyl group substituted by 1 to 3 slfo group. In formula (4), R 201 to R2 04 independently represent a hydrogen atom, or a C1-C4 alkoxy group substituted by a slufo group. |
