摘要： An object of the present invention is to provide a liquid developer for electrophotography or electrostatic recording, wherein such liquid developer achieves good electrophoretic migration property as well as good transferability onto a base material for printing. As a means for achieving the aforementioned object, the present invention provides a liquid developer obtained by dispersing, in an insulating solvent, colored resin particles obtained according to the coacervation method from at least a pigment, pigment dispersion agent and binder resin, wherein the insulating solvent has been mixed in such a way that aliphatic hydrocarbon solvent having 11 to 12 carbon atoms accounts for 8.0 to 20.0 percent by mass, and aliphatic hydrocarbon solvent having 17 to 30 carbon atoms accounts for 2.0 to 45.0 percent by mass, and a total of these aliphatic hydrocarbon solvents having 11 to 30 carbon atoms accounts for 99 percent by mass or more, relative to the total mass of insulating solvent, and also in such a way that the viscosity of the insulating solvent at 25°C becomes 2.0 to 10.0 mPa€¢s.

摘要： In an example of a method for making polymer-encapsulated metallic ink pigment particles, a layer of a transparent resin dispersion is disposed on a flexible substrate. The resin dispersion layer is substantially dried, and a base resin layer is formed. A slurry is disposed onto the base resin layer. The slurry includes metallic pigment particles and polymer particles dispersed in a non-aqueous carrier. The slurry is dried to form a metallic pigment-polymer sheet. Another layer of the transparent resin dispersion is disposed on the metallic pigment-polymer sheet and is dried. A coating resin layer is formed. The metallic pigment-polymer sheet and the base and coating transparent resin layers form a tri-layer film having the metallic pigment particles encapsulated between the base and coating transparent resin layers.
