Colored magnetic particles (10, lOa) 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 (40), and a method for manufacturing the same. The colored magnetic particles (10) include magnetic particle elements (12) and a coloring layer (14) formed on each of the magnetic particle elements (12) from a first dispersion liquid using a coating apparatus (20) of a tumbling, fluidizing and granulating type, to thereby color each of the magnetic particles (12). 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 (10) each include a protective layer (16) formed on the coloring layer (14). The protective layer (14) is formed from a second dispersion liquid constituted of synthetic resin dispersed in water. <IMAGE> |
