LIQUID ELECTROSTATIC PRINTING METHOD

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.
