Non film-forming electrophoresis latex of the fluorinated hydrocarbon solvent

The present invention provides a non-film-forming latex of dispersed particles which may be used in an electrophoretic display, comprising: a) a highly fluorinated liquid solvent, and b) dispersed particles comprising a polymer comprising units according to formula I:wherein each (fcp) is independently selected from highly fluorinated polymer chains and each Q is independently selected from -H and straight or branched non-fluorinated polymer chains (hcp). Latexes of dispersed particles having a very small particle size are especially provided.
