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.
Claims20
A microcapsule having a transparent capsule wall material comprising color particles selected from among color magnetic pigment particles and color pigment particles;
- magnetically color-tunable particles;
- and a curable solvent.
A microcapsule having a transparent capsule wall material comprising therein color particles selected from among color magnetic pigment particles and color pigment particles;
- magnetically color-tunable particles;
- and a solvent,
- wherein the microcapsule comprises color magnetic pigment particles, wherein the color magnetic pigment particles are configured to unevenly distribute within the microcapsule in response to application of an external magnetic or electric field, and wherein the magnetically color-tunable particles are configured to rearrange to a crystal structure in response to the application of an external magnetic or electric field,
- and wherein the color magnetic pigment particles are nanoparticles configured to form a light-reflecting or light-absorbing layer in the microcapsule in response to the application of the external magnetic or electric field, and wherein the magnetically color-tunable particles are configured to retain a substantially random distribution of the crystal structures formed in response to the application of an external magnetic or electric field within the microcapsule.
A microcapsule having a transparent capsule wall material, comprising color particles selected from among color magnetic pigment particles and color pigment particles;
- magnetically color-tunable particles;
- a solvent;
- and a photopolymerization initiator or a thermal polymerization initiator.
