Abstract
An electrophoretic particle including a pigment particle having an intermediate residue covalently bonded to the surface of the pigment particle and a polymer bonded to the intermediate residue. The polymer may be derived from one or more types of monomers and at least one of the monomers is a substituted or unsubstituted styrene monomer including halogenated styrenic monomers. The electrophoretic particle may be used in an electrophoretic medium including a dispersion of the particles in a suspending fluid. The electrophoretic medium may be incorporated into an electro-optic display.
