ABSTRACT:
A colored particulate dispersion is provided, in which the particle diameter of colored particulates is small and dispersion stability is excellent. Also provided is an ink for ink-jet recording in which there is little dependency on paper such that excellent color formation and color tone are obtained when printing on a freely selected paper, and which has excellent water resistance and light resistance. The colored particulate dispersion contains colored particulates that contain an oil-soluble dye and a block copolymer, which is formed of a hydrophobic segment and a hydrophilic segment. The ink for ink-jet recording contains the colored particulate dispersion.
