摘要： In an example, a method includes identifying a contact area of a substrate within which an apparatus will make contact with the substrate and defining a boundary area of the substrate between the contact area and a remaining area of the substrate. Print agent may be printed on the substrate, wherein the print agent is printed at a first coverage in the remaining area, a second coverage less than the first coverage in the contact area; and a gradually reducing coverage across the boundary area from the first to the second coverage.

摘要： Herein is disclosed an electrostatic ink composition. In some examples, the electrostatic ink compositions comprise: a carrier liquid; a first resin; and a fluorescent pigment. The fluorescent pigment comprising a fluorescent dye and a second resin matrix, wherein the second resin is selected from the group comprising polyamide resins, polyvinylchlorides, polyolefin resins, polystyrenes, acrylonitrile-butadiene-styrene resins, polycarbonates, poly acrylic and methacrylic acid resins, polyethylene terephthalates, polyamide resins, polyurethanes, epoxy resins, silicone resins, polyester resins, alkyd resins, acrylonitrile polymers, polyesteramides or combinations thereof.

摘要： 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.
