Abstract:
Disclosed herein is a method for electrostatic printing, wherein the method comprises (a) providing an ink composition comprising particles comprising a resin, wherein the ink composition contains less than 0.3 mg of charge director per g of solids in the ink composition; (b) passing the ink composition between a first electrode and a developer roller, wherein sufficient potential is applied between the developer roller and the electrode such that the resin particles are charged and adhere to the developer roller; (c) transferring at least some of the particles from the developer roller to a photoimaging plate to form an image on the photoimaging plate; and (d) transferring the image from the photoimaging plate to a print medium. Also disclosed here is an apparatus for carrying out the method, and a print medium printed using the method.
