    • PROBLEM TO BE SOLVED: To provide a method for producing a pigment composite having high dispersion stability of a pigment, and small and uniform particle diameters, and a pigment-containing composition. SOLUTION: (1) The method for producing the pigment composite and the pigment-containing composition comprises a step for dissolving the pigment in a fluid in a supercritical state or a subcritical state, and a step for bringing the fluid containing the dissolved pigment into contact with a solution containing a polymer. (2) The production method comprises a step for dissolving the pigment in the fluid in the supercritical state or the subcritical state, and a step for discharging the fluid containing the dissolved pigment into the solution containing the polymer. (3) The production method comprises a step for dissolving the pigment in the fluid in the supercritical state or the subcritical state, a step for bringing the fluid containing the dissolved pigment into a state released from the supercritical state or the subcritical state, and a step for bringing the resultant fluid into contact with the solution containing the polymer.
