| description | The present invention provides a method that enables production of a surface-treated colored inorganic particle with which the desired color tone can be consistently reproduced as intended with no variation occurring in the color tone of the compositions produced with the particle, within each production and over multiple production runs. The invention relates to a method for producing a surface-treated colored inorganic particle, comprising spray drying a mixture of a dispersion [I] and a solution [II], wherein the dispersion [I] is a dispersion of inorganic particles having an average particle diameter of 0.005 to 5 μm dispersed in a solvent with a pigment, and the solution [II] is a solution of a surface treatment agent hydrolyzed in the presence of a hydrolysis aid. |
