Abstract

Disclosed is a microcapsule composed of a transparent capsule wall material and configured to contain therein color particles selected from among color magnetic pigment particles and color pigment particles, magnetically color-tunable particles, and a solvent, thus exhibiting a superior structural color expression effect compared to a conventional microcapsule, and realizing a full range of colors, thereby enabling use thereof as a print medium.

Description

technical field [0001] The present disclosure relates to a microcapsule comprising colored particles, magnetically tonable particles and a solvent, and to various products, devices and methods utilizing the microcapsule. The present disclosure specifically relates to a microcapsule, wherein the colored particles are colored magnetic pigment particles, and the colored magnetic pigment particles can be unevenly distributed in the capsule by means of an external force such as a magnetic field or an electric field, and the colored magnetic pigment particles in the capsule The contained magnetically tunable particles can rearrange into a photonic crystal structure in response to said external force. The microcapsules of the present disclosure can facilitate the achievement of a full range of structural colors and a wide range of contrast ratios. Background technique [0002] Various product authentication or anti-counterfeiting media are being developed using materials whose col...
