    摘要: A reimageable recording medium includes a substrate, a display layer, and a protective layer. The protective layer comprises a microencapsulated diarylethene material that is capable of switching between a UV absorbing and UV transparent state. During an imaging process, the protective layer is switched from a UV absorbing state to a UV transparent state to allow UV light of a sufficient wavelength to convert a photochromic material of the display layer to a colored state to form an image. The protective material is then switched back to a UV absorbing state to prevent the UV light component from a reading source to convert unimaged areas of the display layer to change color, which would reduce the contrast and resolution of the imaged medium.

    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.
