An electrostatic ink composition comprising a carrier liquid; a first resin comprising a copolymer of an alkylene monomer and a methacrylic acid monomer; and a second resin comprising a copolymer of an alkylene monomer and an acrylic acid monomer, wherein the second resin constitutes at least 35 wt. % of the total amount of resin is disclosed.

Liquid electrostatic ink composition

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)

Described herein is a liquid electrostatic ink composition. The composition may comprise: a. a carrier liquid; and b. chargeable particles suspended in the carrier liquid, wherein the chargeable particles comprise a thermoplastic resin formed from the reaction of a first resin and a second resin, wherein i. the first resin comprises a polymer having acidic side groups; and ii. the second resin comprises an epoxy resin component and an elastomeric component, wherein the epoxy resin component has one or more epoxide groups per molecule.

Electrostatic ink composition

Herein is disclosed a liquid electrostatic ink composition. The composition may comprise a liquid carrier having dispersed therein: chargeable particles comprising a thermoplastic resin having acidic side groups; and globular particles comprising a hydrocarbon having a drop point, measured according to ASTM D3954-15, of at least 120&#xb0; C., the globular particles having a D50 of from 2 &#x3bc;m to 7 &#x3bc;m and a D90 of 10 &#x3bc;m or less, the D50 and D90 being measured in the liquid carrier using laser diffraction and volume distribution, in accordance with ISO13220.
