Abstract

An electro-optic display comprises first and second substrates and a lamination adhesive layer and a layer of a solid electro-optic material disposed between the first and second substrates, the lamination adhesive layer having a volume resistivity, measured at 10° C., which does not change by a factor of more than about 3 after being held at 25° C. and 45 percent relative humidity for 1000 hours. The electro-optic material is preferably an encapsulated electrophoretic material. Other desirable characteristics of lamination adhesives for use in electro-optic displays are also described.
