摘要：
The present invention provides coloring particles containing a dye and a water-insoluble low-molecular-weight dispersant, wherein the average particle size of the coloring particles is 10 nm or more and 80 nm or less; the solubility parameter of the dye in water with a pH of 6.0 to 10.0 is 9.20 or more, the solubility parameter being represented by formula (1); and the content of the dye and the content of the water-insoluble low-molecular-weight dispersant satisfy a relationship of formula (2).
