ABSTRACT:
Electrophoretic particles are constituted by core particles comprising a first polymer, and a pigment dispersed in the core particles. To the pigment, a second polymer is grafted, and at the surface of core particle, a shell layer for suppressing agglomeration of the core particles is disposed. The electrophoretic particles are excellent in a degree of coloring and dispersibility compared with conventional electrophoretic particles.
