Abstract
The invention is directed to methods and compositions for improving the adhesion properties and switching performance of an electrophoretic display. The methods and compositions comprise the use of a high dielectric polymer or oligomer and optionally a crosslinking agent.
Claims25
A method for improving the adhesion properties and switching performance of an electrophoretic display wherein display cells are filled with an electrophoretic fluid comprising a solvent, which method comprises (a) applying an adhesive composition to a component of said electrophoretic display, or (b) sealing the filled display cells with a sealing composition, wherein said adhesive or sealing composition comprises
- (i) a polymer or oligomer having a dielectric constant higher than that of the solvent,
- (ii) a radically or photochemically graftable polymer, wherein the polymer or oligomer of (i) is grafted onto the graftable polymer of (ii),
- (iii) optionally a crosslinking agent, and
- (iv) a catalyst which is optionally present when the crosslinking agent is present.
