| 摘要 |
The present invention relates to a magnetic particle having a high-reflective protective membrane and a method for producing same, especially wherein the magnetic particle includes a magnetic core, a shell formed on the magnetic core, and a high-reflective protective membrane formed on the shell, and the high-reflective protective membrane has low-refractive-index and high-refractive-index membranes. The magnetic particle has advantages that have high brightness and prevent the shell from being damaged by friction with a filler and pressure between rollers during a dispersion step of an ink-making process. Also, the magnetic particle is used for different colored inks, general paint, particulate pigments for vehicles, pigments for cosmetics, catalyst paint, and especially anti-forgery inks, etc., and has advantages that are durable and express colors that existing magnetic pigments fail to. |
