PROBLEM TO BE SOLVED: To provide a black ink for inkjet, which shows little change in a hue by influences of color rendering property and is excellent in injection stability and storage stability.SOLUTION: The black ink for inkjet is to be used for a disperse dye ink for textile printing, and the ink includes: a water-soluble organic solvent containing glycol ether; and a disperse dye comprising a first disperse dye having a maximum absorption wavelength in a wavelength region from 640 nm to less than 680 nm, a second disperse dye having a maximum absorption wavelength in a wavelength region from 590 nm to less than 640 nm, and a third disperse dye and a fourth disperse dye, which are different from the first disperse dye and the second disperse dye and have maximum absorption wavelengths less than 590 nm, each in UV-visible spectral absorption measurement in a solution state of the dye dissolved in acetone. |
