The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.
Polymeric dyes that comprise (a) segments that render the dyes soluble or dispersible in hydrocarbon solvents and (b) segments that impart color. The polymeric dyes can be introduced into hydrocarbon solvents or formed in hydrocarbon solvents to form stable colored dispersions, which can be used as toners for electrophotography. In these toners, the polymeric dye contains macromeric moieties that render the polymeric dye dispersible in hydrocarbon solvents. The polymeric dye may contain either a charge-directing chelating moiety or a surface-release promoting moiety or both of these moieties.

An electrostatic liquid toner imaging process uses a liquid toner comprises a perfluorinated solvent and polymer resin-bound pigment particles. The polymer resin is preferably a resin containing highly fluorinated or perfluorinated units within the polymer resin or a resin comprising of at least 10% perfluorinated units, the rest comprising nonfluorinated units.
