Abstract

Described herein is a liquid electrophotographic printing process comprising heating a coating composition comprising a thermoplastic polymer and a liquid carrier to dissolve the thermoplastic polymer in the liquid carrier and form a heated coating solution; and applying the heated coating solution to a liquid electrophotographically printed layer disposed on a substrate. The thermoplastic polymer may be selected from a copolymer of ethylene and an alk-1-ene and a copolymer of ethylene and 50 wt. % or less vinyl acetate; and the liquid carrier may comprise a hydrocarbon, a silicone oil or a vegetable oil. Also described herein are a liquid electrophotographic printing kit comprising a liquid electrophotographic ink composition and a coating composition, as well as a liquid electrophotographic printer.
