Abstract:
A method for preparing a pigment dispersion includes milling a starting pigment dispersion containing a pigment and optionally a carrier and a dispersant with milling media having an average particle size of about 100 μm or less, until a final pigment dispersion having at least one of a desired pigment average particle size and a desired pigment particle size distribution is obtained; optionally separating the milling media from the final pigment dispersion; and optionally diluting the final pigment dispersion to obtain a desired pigment particle concentration.
