Provided in one example herein is a liquid electrophotographic varnish composition. The composition includes resin particles each including a polymeric resin mixture, which includes a first polymeric resin including an ethylene-based polymer; and a second polymeric resin including a polyamide. The composition also includes a carrier fluid.

Varnish compositions

In one aspect, the present disclosure relates to a liquid electrophotographic electrode ink composition comprising: a thermoplastic polymer comprising a copolymer of an olefin and acrylic acid and/or methacrylic acid; an electroactive material comprising a lithium intercalation material; a charge adjuvant, and a liquid carrier.

Electrophotographic ink composition including copolymer of olefin and (meth) acrylic acid and charge adjuvant

The present disclosure discloses a liquid electrophotographic ink. The ink can include (A) a liquid vehicle; (B) at least one colorant; (C) a resin comprising an ethylene acid copolymer; (D) an ethylene/(meth)acrylic acid C1-10 alkyl ester copolymer selected from the group consisting of an ethylene/methyl acrylate copolymer and an ethylene/butyl acrylate copolymer; and (E) a condensation product of urea and aldehyde.

Liquid electrophotographic ink(s)

The present disclosure relates to an electrophotographic composition that comprises a polymer resin mixture and a liquid carrier. The polymer resin mixture comprises (i) an olefin polymer A having acid and/or ester side groups and a melt index of 22 to 100 g/10 min; and (ii) an olefin polymer B having a melt index of 1 to 20 g/10 min. The olefin polymer B forms 1 to 50 weight % of the polymer resin mixture.

Electrophotographic composition

The present disclosure relates to a liquid electrophotographic composition comprising: a polymer resin comprising a side group comprising a cross-linkable moiety; and a carrier liquid.

Liquid electrophotographic composition

A transparent electrophotographic varnish composition comprises a charge adjuvant and inorganic filler particles. A method of manufacturing an electrophotographic varnish composition comprises heating a thermoplastic resin mixture until the resin has melted; cooling the resin mixture to form resin particles; contacting the resin particles with a charge adjuvant and inorganic filler particles to form composite particles or a mixture of particles; and combining the composite particles or particulate mixture with a carrier fluid to form the electrophotographic varnish composition. A liquid electrophotographic printing system and a print substrate are also provided.

Electrophotographic varnish

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.

Liquid electrophotographic varnish composition

An electrophotographic varnish composition that comprises, in a liquid carrier, a polymeric resin; an epoxy-based cross-linking agent, a mono-epoxy diluent and a metal catalyst and/or a photo-initiator. Also described herein is a method for making such electrophotographic varnish composition.

Electrophotographic varnish composition

Herein is disclosed a liquid electrophotographic varnish composition comprising: a polymer resin; an epoxy-based cross-linking agent; a metal catalyst and/or a photo-initiator for catalyzing the cross-linking; and a carrier liquid.

The present disclosure discloses a liquid electrophotographic ink. The ink includes a liquid vehicle, an ethylene acid copolymer, and an ethylene/(meth)acrylic acid C1-10 alkyl ester copolymer. Also disclosed is a method for the manufacture that ink and a method for performing a liquid electrophotographic process by printing a substrate with the ink.

Liquid electrophotographic ink

The present invention relates to a liquid electrophotographic ink comprising a carrier liquid, a pigmented resin composite dispersed in the carrier liquid, and about 0.15 to about 10% (w/w) of an organic wax. The liquid electrophotographic ink is typically formulated for printing in a liquid electrophotographic printer.
