摘要： There are provided a pigment-containing coloring material stably dispersible in a high concentration in various organic solvents, and a process for producing the same. The production process of the coloring material is characterized by comprising the steps of: providing a solution comprising (1) a soluble pigment precursor which is convertible into an insoluble pigment, (2) a solvent capable of dissolving the soluble pigment precursor therein, and (3) a stabilizing agent comprising an organic compound having a structure or a functional group capable of stabilizing the dispersibility of the insolubilized pigment in the solvent; and converting said soluble pigment precursor into an insoluble pigment to obtain the coloring material containing the insolubilized pigment dispersed stably in the solvent.
