A liquid electrophotographic ink composition is described. The liquid electrophotographic ink composition comprises a ceramic pigment, a polymer resin, a glass frit, and a liquid carrier. Also described is a heat transferable printed image, a process for printing a heat transferable image and a process for heat transfer printing using the liquid electrophotographic ink composition.

A method is disclosed. The method may comprise applying a coating of electrically charged fluid print agent to a developer surface, the fluid print agent comprising particles of thermoplastic resin in a carrier fluid. The method may further comprise controlling migration of fluid print agent from the developer surface to form an image from fluid print agent on a first surface. The method may further comprise irradiating the print agent on the first surface with ultraviolet radiation to heat the print agent to a temperature of at least 70° C. to melt the thermoplastic resin. A print system and a heating unit are also disclosed.

The present disclosure relates to an electrophotographic printing method comprising electrophotographically printing a liquid electrophotographic composition onto a substrate. The liquid electrophotographic composition comprises a charge adjuvant and a copolymer of a) ethylene and b) methacrylic acid and/or acrylic acid, wherein 80 to 95 weight % of the units of said copolymer are derived from ethylene. The printed substrate is then subjected to electron beam (EB) radiation.
