An electrostatic ink composition comprising:
- a carrier liquid;
- a first resin comprising a copolymer of an alkylene monomer and a methacrylic acid monomer, wherein the first resin constitutes from 40 wt. % to 65 wt. % of a total amount of resin;
- a second resin comprising a copolymer of an alkylene monomer and an acrylic acid monomer, wherein the second resin constitutes from at least 35 wt. % to 60 wt. % of the total amount of resin;
- and
- a third resin comprising a copolymer of an alkylene monomer and a vinyl ester monomer, wherein the third resin constitutes from 0.5 wt. % to 9.5 wt. % of the total amount of resin;
- wherein the first resin and the second resin and the third resin are present in a ratio (wt./wt./wt.) of 45:50:5.
