Abstract: The invention relates to a liquid toner and imaging apparatus provided with an imaging surface having a liquid toner image formed thereon on fibrous toner particles and carrier liquid. The fibrous toner particles can be composed of a polymer portion and pigment dispersed therein, where the polymer portion comprises a surface of the fibrous toner particles and is insoluble in the carrier liquid at temperatures below 40° C., so that the polymer portion will not dissolve or solvate in storage. The polymer portion also is solvatable by the carrier liquid only at temperatures above 50° C. The carrier liquid has, as a major component, first liquid hydrocarbon having a first rate of evaporation, and, as a minor component, second liquid hydrocarbon having a second rate of evaporation which, at room temperature, is at least an order of magnitude less than the first rate of evaporation.

Abstract: In a liquid toner for use in imaging processes which comprises pigmented polymer particles, at least one charge director and a hydrocarbon liquid toner carrier, the polymer is a blend of at least two distinct polymer components, the blend being characterized in that in a 40% non-volatile mixture with a hydrocarbon liquid toner carrier, it has on a semi-logarithmic viscosity vs. temperature cooling curve, a break-point at a temperature below about 65.degree. C. at a viscosity of between about 3.times.10.sup.5 centipoises and about 5.times.10.sup.6 centipoises. The polymer blend and an electrostatic imaging process (particularly one using an intermediate transfer member) utilizing the above toner are also claimed. Use of such polymer blends enables liquid toner to be applied in such processes at no more than and in some cases less than the customary processing temperatures.

Abstract: A printing process for forming high contrast color images on polymer surfaces, comprising: (a) forming a layer of substantially opaque liquid toner comprising polymer based toner particles and a carrier liquid, on an imaging surface; (b) transferring the layer to an intermediate transfer member; (c) heating the layer on the intermediate transfer member to a temperature at which the toner particles at least partially coalesce; (d) repeating (a) to (c) sequentially for at least one subsequent layer in at least one subsequent layer in at least one color, said at least one subsequent layer being transferred to the intermediate transfer member onto the opaque layer to form multiple layers on the intermediate trnsfer member; and (e) transferring the multiple layers to a polymer surface.
