Abstract

There is provided a process for preparing a laminate, comprising electrostatically printing a transparent electrostatic ink composition onto a base material, wherein the transparent electrostatic ink composition comprises a thermoplastic resin, and a charge adjuvant and/or a charge director; providing a substrate; and contacting the substrate with the transparent electrostatic ink composition while the thermoplastic resin is softened or molten, and then allowing the thermoplastic resin to harden, so that the electrostatic ink composition adheres the base material and the substrate together. Laminate materials are also disclosed.
