    摘要： Described herein is a liquid electrostatic ink composition. The composition may comprise: a. a carrier liquid; and b. chargeable particles suspended in the carrier liquid, wherein the chargeable particles comprise a thermoplastic resin formed from the reaction of a first resin and a second resin, wherein i. the first resin comprises a polymer having acidic side groups; and ii. the second resin comprises an epoxy resin component and an elastomeric component, wherein the epoxy resin component has one or more epoxide groups per molecule.

    摘要： Herein is described a liquid electrostatic printing method comprising providing a liquid electrostatic ink composition comprising a carrier liquid and chargeable particles comprising a resin; and providing an adhesion promoting composition comprising an adhesion promoter. The liquid electrostatic ink composition is contacted with a latent electrostatic image disposed on a surface to create a developed ink image. The developed ink image is transferred to an intermediate transfer member. The adhesion promoting composition is deposited on the intermediate transfer member to form an adhesion promoting layer. The adhesion promoting layer and the developed ink image are transferred to a print substrate, such that the adhesion promoting layer is disposed on the print substrate and the developed ink image is disposed on the adhesion promoting layer.

    摘要： Herein is disclosed a method of printing comprising the steps of applying an ink comprising a thermoplastic resin to a print substrate using an electrostatic printing process; and applying an overcoat composition comprising a crosslinking agent to the ink after applying the ink to the print substrate, such that the thermoplastic resin of the ink becomes crosslinked on the print substrate due to interaction with the crosslinking agent.

    摘要： Herein is disclosed a method of printing comprising the steps of: (a) applying an ink comprising a thermoplastic resin to a print substrate using an electrostatic printing process; and (b) applying an overcoat composition comprising a crosslinking agent to the ink on the print substrate, such that the thermoplastic resin of the ink is crosslinked. Print substrates and printing systems are also disclosed.
