POLYHYDROXY COMPOSITIONS FOR SEALING ELECTROPHORETIC DISPLAYS
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.

At least one of the basecoat materials includes the aqueous coating. Also described herein are multicoat paint system obtainable by this method, and the use of at least one polycarboxylic acid in an aqueous coating composition for improving the effect pigment orientation, or for color matching.
