(57) [Summary] A solubility in an aqueous solvent is 0.1% by weight. An ultrafine pigment dispersion having a pigment concentration of 0.1% by weight or more containing a pigment having a particle diameter of 200 nm or less, obtained by dissolving a pigment having a particle diameter of less than 1 in a water-soluble polymer and then dispersing the pigment in an aqueous solvent. The present invention provides a dye dispersion having extremely high transparency, useful as an inkjet ink, a water-based ink, and a water-based paint, and capable of forming a clear image. |
