PROBLEM TO BE SOLVED: To provide a pigment dispersion material for a color filter, which shows a sharp grain size distribution and achieves both a high contrast and viscosity stability required for a color filter, by producing the pigment dispersion material by use of a wet dispersing machine using micromedia having a diameter of 0.1 mm or less, in which exposure of particle active surfaces is suppressed, the pigment is efficiently and finely dispersed into a sub-micron region of 1 μm or less, and re-aggregation of the pigment is prevented.SOLUTION: A production method of a pigment dispersion material for a color filter is provided, which includes: a dispersion step (A) of dispersing a pigment mixture comprising a pigment, a resin, and a solvent in a wet dispersing machine using media having a particle diameter of larger than 0.1 mm to obtain a pigment dispersion material (i) having an average particle diameter of 40 to 200 nm; and a dispersion step (B) of dispersing the pigment dispersion material (i) in
