发明名称 Colored magnetic particles for magnetophoretic display and method for manufacturing same
摘要 Colored magnetic particles for magnetophoretic display capable of substantially preventing peeling of a pigment therefrom, to thereby prevent contamination of a dispersion medium during use of a magnetophoretic display panel, and a method for manufacturing the same. The colored magnetic particles include magnetic particle elements and a coloring layer formed on each of the magnetic particle elements from a first dispersion liquid using a coating apparatus of a tumbling, fluidizing and granulating type, to thereby color each of the magnetic particles. The first dispersion liquid is constituted of a coloring pigment, synthetic resin and water. The synthetic resin is in the form of an aqueous emulsion. The colored magnetic particles each include a protective layer formed on the coloring layer. The protective layer is formed from a second dispersion liquid constituted of synthetic resin dispersed in water.
