PROBLEM TO BE SOLVED: To provide a watercolor ink that uses a color-material-containing fine granule of a core/shelter type and is superior in color reproducibility. SOLUTION: When an ink is prepared with the color-material-containing fine granule constituting of a polymer core containing a color material and a polymer shell by using its dispersion liquid, its maximum absorption wavelength becomes 500 to 600 nm and, when the ink is diluted to make its absorbance to be 1, the absorbance at 800 nm results in 0.1. |
