| 发明名称 | Preparation of pigment dispersions and toner compositions | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method for preparing a pigment dispersion, the method comprising: 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 and being comprised of diamond dust, 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; separating the milling media from the final pigment dispersion; and diluting the final pigment dispersion to obtain a desired pigment particle concentration. | ||
