||Electronic paper displays (EPD) offers both benefits of a paper readability and a reflective display that can change contents, such as all electronic displays. Electronic ink composed of encapsulated pigment particles, one of the various components of the electronic paper display, can receive electrical signals to adjust the color and the pattern of the display surface. When pigments are applied to the EPD without encapsulating the particles, the weatherability and the light fastness of the pigment are lowered, and the driving stability of the EPD is deteriorated due to various shapes and sizes. In this study, copolymer-encapsulated phthalocyanine green 7 pigment particles were prepared by dispersion polymerization of styrene, divinylbenzene and hydroxyethyl methacrylate. The polymer encapsulated color pigment particles are expected to be widely used in fields such as fashion, advertising, and electronic skins.
