ABSTRACT:
The present invention relates to novel fluorinated dyes or colorants having high solubility and low viscosity in halogenated, especially fluorinated, solvents. The dyes or colorants of the present invention have shown to improve the performance of electrophoretic displays. The invention is particularly directed to a fluorinated porphyrin dye or colorant expressed by Formula (VII).
