More Information
Summary:Herein is disclosed a magenta liquid electrostatic ink composition comprising chargeable particles comprising a resin, a pigment, a liquid carrier in which the chargeable particles are dispersed, and a charge director, wherein the resin is formable from polymerizing alkylene monomers and methacrylic or acrylic acid monomers, the pigment is selected from pigment violet 19 type αI pigment violet 19 type αII pigment violet 19 type β, pigment violet 19 type γ, pigment red 177, pigment red 208, pigment red 122 and pigment violet 32, and the liquid electrostatic ink composition lacks any other types of pigment. Also disclosed herein is a method of electrostatic printing and a print substrate having printed thereon the magenta liquid electrostatic ink composition.
