E Ink Corporation, David J Cole, November 23, 2004: US06822782 (247 worldwide citation)

In electrophoretic media, it is advantageous to use pigment particles having about 1 to 15 percent by weight of a polymer chemically bonded to, or cross-linked around, the pigment particles. The polymer desirably has a branched chain structure with side chains extending from a main chain. Charged or ...
