<p>The present invention relates to a magnetic particle having a highly reflective protective film and to a method for manufacturing same. More particularly, the present invention relates to a magnetic particle having a highly reflective protective film and to a method for manufacturing same, wherein the magnetic particle comprises a magnetic core, a shell formed along an outer periphery of the magnetic core, and a highly reflective protective film formed along an outer periphery of the shell, wherein the highly reflective protective film includes a film having a low refractive index and a film having a high refractive index. The magnetic particle is advantageous in that it has high luminosity and prevents friction with a filler and damage to the film of the shell caused by the pressure between rolls during the distribution step of an inking process. The magnetic particle can be used in colored ink, general paint, powder pigments for vehicles, cosmetic pigments, and catalytic pigments. Particularly, the magnetic particle is advantageous in that it can be used as security ink for a value document in order to express a range of colors which may not be expressed by existing magnetic pigments, and in that it is durable.</p> |
