Abstract

In electrophoretic media, it is advantageous to use pigment particles having polymer shells comprising from 0.1 to 5 mole per cent of 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.
