A liquid electrophotographic varnish composition comprising: a polymer resin; an epoxy-based cross-linking agent; a solid catalyst comprising at least one amine group; and a carrier liquid.

A printing sheet is formed of a base material film, a toner fixing layer formed on one principal surface of the base material film, a planarization layer formed on the other principal surface of the base material film, an adhesive layer formed on the surface of the planarization layer, and a peeling film stuck on the surface of the adhesive layer. The base material film has a laminated structure composed of a white foamed PET film layer on the toner fixing layer side and a transparent non-foamed PET film layer on the adhesive layer side, and the strength of the printing sheet is improved by the combined use of the non-foamed PET film. The planarization layer is formed of a colored ink layer, e.g. white ink layer, and increases the bonding area of the adhesive layer with the base material film side, thereby achieving smooth peeling from an adherend.

A process for preparing a printed rigid plastic substrate is described, the process comprising: providing a rigid plastic substrate comprising a primer on a surface of the rigid plastic substrate, the primer comprising a primer resin; printing a liquid electrophotographic ink composition comprising a thermoplastic resin onto the primer on the surface of the rigid plastic substrate; depositing a cross-linking composition comprising a cross-linker onto the printed electrophotographic ink composition disposed on the primer; and laminating the rigid plastic substrate with a flexible film such that the ink composition and the cross-linker are disposed between the rigid substrate and the flexible film and wherein the lamination of the rigid substrate with the flexible film causes cross-linking of the thermoplastic resin of the ink composition and of the primer resin.
