PROBLEM TO BE SOLVED: To provide a method for adjusting the concentration of an aqueous pigment dispersion able to adjust the concentration of the aqueous pigment dispersion by dilution, free from the troubles of the sedimentation and aggregation of the pigment in the aqueous pigment dispersion after dilution, and able to make the dispersion excellent in storage stability, color hue stability with the laps of time, and the like. SOLUTION: The concentration of an aqueous pigment dispersion is adjusted with a diluting agent comprising (A) an inorganic powdery body, (B) a dispersant, (C) an aqueous solvent and (D) a water-soluble thickener, whose construction ratio is 2-70 wt.%, 1-10 wt.%, 20-97 wt.% and 0-3 wt.% for the components A, B, C and D, respectively.
