<p>PROBLEM TO BE SOLVED: To provide an inkjet yellow ink composition comprising C.I.Disperse Yellow 114, which has good storage stability and gives a yellow dyed product excellent in color developing property and light fastness.SOLUTION: The inkjet yellow ink composition comprises C.I.Disperse Yellow 114, a dispersion dye having a polycyclic structure, and a water-soluble organic solvent. A hue angleθin Labcolor system calculated from spectral characteristics of the ink composition is in the range from 100 to 116°; and a content percentage of the dispersion dye having a polycyclic structure is 0.001 parts by mass or more with respect to 1 part by mass of the C.I. Disperse Yellow 114.</p> |
