The present invention is directed to a sealing layer that comprises a poly(vinyl alcohol) homopolymer or a poly(vinyl alcohol-co-ethylene) copolymer, a polyurethane, and a conductive filler. The sealing layer shows good barrier properties to a non-polar fluid. The sealing layer can be used to seal microcells of electro-optic devices, contributing to improved good electro-optic performance of the device, especially at low temperatures. |
