REFRACTIVE INDEX MATCHED RESIN FOR ELECTROPHORETIC DISPLAYS AND OTHER APPLICATIONS
Embossing resins, methods of manufacturing such resins, and electrokinetic display system, which includes display cells containing such resins. The resins include a fluoropolymer in weight percentage 5%-60%, a difunctional diluent in weight percentage 0-30%, a monofunctional diluent in weight percentage 0-40%, a urethane diacrylate or functionalized nanoscale material, e.g., a functionalized urethane material, in weight percentage 5-50%, a photoinitiator in weight percentage 0.5-5%, and a surfactant in weight percentage less than 0.5%. The difunctional diluent may be Hexanediol Diacrylate, and the monofunctional diluent may be a monofunctional hydrocarbon. The resins are made by identifying a target index of refraction for a cured state thereof, and combining together, by weight percentage, the constituent components to produce the liquid state version of the embossing resin having a desired composite index of refraction.
