Abstract

The present invention relates to particles for electronic paper and to a manufacturing method thereof. The method for manufacturing particles for electronic paper, comprises the steps of: dispersing electronic paper particle compositions containing a polymer resin, a charge controlling agent, and a pigment by using a solvent to obtain sprayable compositions; spraying the sprayable compositions at a predetermined pressure to generate a liquid droplet; drying the liquid droplet; and obtaining particles for electronic paper from the dried liquid droplet. The method of the present invention can manufacture particles for electronic paper without using a stabilizer or an emulsifier, thereby improving charge stability of particles for electronic paper, and providing better environmental stability against contamination.
