摘要： Here is described a method of printing on a plastic substrate, the method comprising: providing an electrostatic ink composition comprising a carrier liquid, and particles comprising a resin, and a slip agent dispersed in the carrier liquid; forming a latent electrostatic image on a surface; contacting the surface with the electrostatic ink composition, such that at least some of the particles and the slip agent are transferred to the surface to form a developed toner image on the surface; and transferring the toner image to the plastic substrate. Electrostatic ink compositions and plastic substrates are also disclosed.

摘要： In an aspect, there is provided a method of foil printing that may comprise providing a substrate having a surface comprising a first area and a second area, wherein the first area has printed thereon a first electrostatic ink composition comprising a first thermoplastic resin and substantially lacking a pigment and the second area has printed thereon a second electrostatic ink composition comprising a second thermoplastic resin and a pigment; applying a liquid solvent composition to the first electrostatic ink composition on the first area and the second electrostatic ink composition on the second area, to swell the first and second thermoplastic resins; and contacting a foiling material with the first electrostatic ink composition on the first area, such that the foiling material selectively adheres to the first area on the surface of the substrate. In another aspect, an electrostatic and foil printing system for performing the method is provided.
