An electroluminescent cell can comprise a first electrode; a second electrode; and an electroluminescent layer disposed between the first electrode and the second electrode. The second electrode can comprise a light-transmitting electrode layer that can comprise electrically conductive regions interspersed by light-transmitting regions. The light-transmitting regions can have higher light-transmissivity than the electrically conductive regions.

Electroluminescent cells

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

According to an example, an electrophotographic ink may include an adsorbent, a volatile fragrance, a resin and a carrier liquid.

Electrophotographic ink including a volatile fragrance

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

This disclosure relates to a liquid electrophotographic composition comprising a thermoplastic polymer resin, a charge adjuvant, microspheres, and a liquid carrier. Each microsphere comprises a shell of material encapsulating a gas. The microspheres are present in an amount of 5 to 90 weight % of the total weight of solids in the 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.
