Abstract
Disclosed herein are novel liquid toner compositions that are suitable for developing electrostatic images. The toner compositions of the present invention comprise pigment, dye, and a polymer, the combination being suspended in an aliphatic saturated hydrocarbon. The improvement in the performance of these toners is due to the presence of small, but significant amounts of dyes which are capable of modifying the surface characteristics of the toner pigment particles.
