Abstract:
A method of protecting an electrostatic image on a substrate, wherein, an electrostatic image is formed on the substrate, and protected by applying an amphipathic liquid toner on the electrostatic image by electrostatic means, and fixing the amphipathic liquid toner to form a protective layer. The amphipathic liquid toner includes a carrier fluid, an amphipathic, non-gel copolymer, and a charge control agent to provide an electrostatic charge. The carrier fluid is typically an electrically resistive hydrocarbon solvent, having an electrical resistivity of at least about 10. sup. 9 ohm. cndot. cm, a dielectric constant of less than about 3, and a boiling point from about 68. degree. C. to about 250. degree. C. The amphipathic, non-gel copolymer, which is insoluble as a whole in the carrier fluid, has at least one polymer segment that is soluble in the carrier fluid and at least one polymer segment that is insoluble in the carrier fluid.
