Abstract
Core-shell coated pigment particles are prepared by core-shell coating using pigment particles, at least one hydrophilic organometallic compound, at least one hydrophobic organometallic compound, distilled water and a solvent. Ink particles coated with an ionized organometallic compound are prepared by using the core-shell coated pigment particles, the solvent and a halogen compound. The ink particles, a dispersing agent and a dielectric liquid are mixed to prepare an ink composition. The ink composition has an electrophoresis property to exhibit an electric movement and has a good dispersibility in a dielectric liquid. The ink composition may be applied in a reflective type color display device.
