Abstract
A dielectric suspension for use in an electrophoretic image display, electrostatic printing or the like, comprising a suspension medium including a dense fluorinated solvent and a less dense hydrocarbon solvent, a plurality of pigment particles dispersed in the suspension medium, a fluid dye dissolved in the suspension medium for providing a contrast with the pigment particles, and a charge control agent adsorbed on the pigment particles for preventing the pigment particles from agglomerating.
