Abstract: A printer includes an image formation portion, a feed portion, and a transfer portion. The image formation portion transfers formed first and second patterned marking agent layers from a photoconductor member onto an intermediate transfer member. The feed portion directs a portion of a foil layer to become adhered, according to the pattern, onto the first marking agent layer on the intermediate transfer member before the second marking agent layer is transferred onto, and becomes adhered to, the foil portion. The transfer portion causes transfer of the foil portion from the intermediate transfer member, via transfer of at least the second marking agent layer from the intermediate transfer member, onto a substrate.

Abstract: Disclosed herein is a liquid electrophotographic ink composition comprising a first resin comprising a copolymer of an alkylene monomer and a methacrylic acid monomer; a second resin comprising a copolymer of an alkylene monomer and from about 5 wt. % to about 11 wt. % of an acrylic acid monomer; and a colorant in an amount of at least 20 wt. % of the solids of the electrophotographic ink composition. Also disclosed herein is a method of producing a printed substrate from the liquid electrophotographic ink composition.
