Abstract
In electrophoretic media, it is advantageous to use pigment particles having a polymer chemically bonded to, or cross-linked around, the pigment particles, the polymer comprising repeating units derived from a fluorinated acrylate or fluorinated methacrylate monomer. The polymer desirably has a branched chain structure with side chains extending from a main chain. Desirably, the fluorinated acrylate or fluorinated methacrylate monomer comprises from 1 to 5 mole percent of the polymer.
