    摘要： A cholesteric display including a liquid crystalline mixture having a dipolar dopant dissolved in the liquid crystalline mixture and the resulting mixture is reflecting light in the visible range of the spectrum when in planar state. In accordance with another aspect, a process includes forming a composition with a dipolar molecule to result in a liquid crystal dipolar dopant, and liquid crystal is added to the composition. In accordance with still another aspect, a device includes a liquid crystal composition includes a cholesteric liquid and a dipolar dopant. The liquid crystal composition is switchable between a focal-conic state and a planar state in the presence of an electric field and is stable in the respective state when the electric field is removed.

    摘要： A method for making toners to include at least one nanoscale fluorescent pigment particle composition and/or a fluorescent organic nanoparticle composition. The particles are incorporated into emulsion of toner and used in making toner via emulsion aggregation. Such toners may have a core and/or a shell and the clay composites may be included within the core, the shell or both. The fluorescent organic nanoparticle composition includes a polymeric matrix obtained by modified EA latex process and/or emulsion polymerization and one or more fluorescent dyes and the nanoscale fluorescent pigment particle composition includes pigment molecules with at least one functional moiety, and a sterically bulky stabilizer compound including at least one functional group, the functional moiety of the pigment associates non-covalently with the functional group of the stabilizer, and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale-sized pigment particles.

    摘要： A toner set includes a plurality of toners, at least one toner but less than all toners of the toner set including binder, colorant and fluorescence agent and remaining additional toners including binder, colorant and free of fluorescence agent. At least a first toner grouping and a second toner grouping of the toner set form a combination, the first and second groupings of the combination exhibiting a substantially same color under ambient light conditions upon image formation. The first toner grouping and the second toner grouping of the combination contain a different amount of the fluorescence agent, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the first toner grouping as compared to the second toner grouping.
