Beschreibung
Zusammenfassung:	The present invention is directed to novel non-aqueous capsules suitable as display cells for an electrophoretic display and the encapsulation process for their manufacture. The present invention is also directed to an encapsulation process for the preparation of non-aqueous capsules suitable as display cells for an electrophoretic display. The process comprises emulsifying an internal phase comprising pigment particles or pigment-containing microparticles dispersed in a halogenated solvent and a halogenated shell-forming material into an external phase comprising a complementary chain extender or crosslinker in an organic solvent.
