Abstract

See full text

Polyhydroxy sealing formulations for the production of electrophoretic displays, and portions thereof, for example, front plane laminates. When the disclosed polyhydroxy compounds are included in a sealing layer (or in a binder layer), the layer has improved wetting properties, allowing for more consistent application of the layer in a roll-to-roll production process. Additionally, the polyhydroxy compounds can migrate into the electrophoretic medium, where they improve the contrast ratio and reduce ghosting.
