Estimating the term…
The invention relates to a novel electrophoretic dispersion comprising a fluorinated solvent as the continuous phase, charged pigment particles or pigment containing microcapsules as the dispersed phase, and the charge of the pigment particles is provided by a charge controlling agent comprising: (i) a soluble fluorinated electron accepting or proton donating compound or polymer in the continuous phase and an electron donating or proton accepting compound or polymer in the dispersed phase; or (ii) a soluble fluorinated electron donating or proton accepting compound or polymer in the continuous phase and an electron accepting or proton donating compound or polymer in the dispersed phase.
An electrophoretic dispersion comprising a fluorinated solvent as the continuous phase, charged pigment particles or pigment containing microcapsules as the dispersed phase and a charge controlling agent which comprises:
An electrophoretic display which comprises:
An electrophoretic dispersion comprising a fluorinated solvent as the continuous phase, charged pigment particles or pigment containing microcapsules as the dispersed phase and a charge controlling agent comprising soluble fluorinated donor/acceptor moiety and a complementary acceptor/donor moiety in the same molecule wherein said fluorinated donor/acceptor moiety is compatible with the continuous phase and the complementary acceptor/donor moiety is incompatible with the continuous phase.
