摘要:
Toner particles and a dry-powder electrophoretic display employing such particles are disclosed herein. The toner particles adapted for a dry-powder electrophoretic display comprise emulsion/aggregation particles having a negative charge. At least a portion of the toner particles include a surface coating, comprising a methacrylate polymer, disposed on the surface of the toner particles to impart a positive charge to a set of toner particles. The emulsion/aggregation toner particles have a particle size generally less than about 10 micrometers that allows for improved image quality as compared to conventional toners utilized in dry-powder electrophoretic displays.
