Abstract

An electrophoretic medium comprises an electrophoretic layer, a layer of lamination adhesive and a polymeric layer disposed between the electrophoretic layer and the lamination adhesive layer, the polymeric layer being impermeable to the fluid. A second form of electrophoretic medium has a layer of a complex of an alkali metal and a polymer in contact with the electrophoretic layer. A third form of electrophoretic medium comprises a plurality of discrete droplets of internal phase in a binder, and further comprises a salt.
