Abstract (en)

[origin: WO8909433A1] An electrostatic method is disclosed for providing multicolor imaging from a single toner bath. The toner bath is a blend of individual toners, each of which contains a color precursor different from the others. This invention also relates to electrostatic imaging systems, and, more particularly, color-self-developing toner particles and processes for the fabrication and use thereof. A blend of these toner particles is useful in multicolor electrostatic imaging using a single dry or liquid toner bath. Potential applications include full-color xerographic copying, full-color printing, full-color computer-generated imaging, and the like.
