Colored particles

A method for manufacturing colored particles containing a dye and a dispersant, the method comprising the steps of:

• emulsifying a mixed solution, in which a first liquid and a dye are mixed, and a second liquid so as to obtain a miniemulsion containing dispersoids;
• and
• removing the first liquid from the dispersoids,
• wherein the dispersant is selected from the group consisting of dodecylbenzene sulfonate, decylbenzene sulfonate, undecylbenzene sulfonate, tridecylbenzene sulfonate, nonylbenzene sulfonate, sodium salts, potassium salts, and ammonium salts thereof, sodium dodecyl sulfate, cetyl trimethyl ammonium bromide, hexadecylpyridinium chloride, hexadecyl trimethyl ammonium chloride, and oxyethylene based alkyl ethers,
• wherein the solubility index represented by Formula (1), as described below, of the dye relative to water is 9.20 or more relative to any water having a pH of 6.0 to 11.0, and
• the dye content and the dispersant content in the colored particles satisfy the relationship represented by Formula (2), as described below:
• solubility index=log(1/(solubility of dye in water (mol/L)) Formula (1)
• 3/2≦(dye content in colored particles)/(dispersant content in colored particles) Formula (2)
• wherein, the dye content in colored particles and the dispersant content in colored particles are on a mass basis.
