    Abstract: 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.

    Abstract: An image forming medium includes a substrate, and an imaging layer coated on or impregnated into said substrate, wherein the imaging layer includes an imagi ng composition including a photochromic or photochromic-thermochromic material dissolved or dispersed in a solvent or polymeric binder, wherein the imaging composition is imageable by light of a first wavelength and erasable in a short time period by a combination of heat and light of a second wavelength such that simultaneous erase with heat and light of the second wavelength is faster than erase by heat alone a nd exhibits a reversible transition between a colorless and a colored state.

    Abstract: Disclosed is a method of embedding machine readable information on a substrate, including converting the information to machine readable code format and writing the machine readable code format on the substrate with at least one fluorescent marking material. Also disclosed is a system for embedding and recovering machine readable information on a substrate, including an image forming device containing at least one fluorescent marking material, wherein the image forming device receives data representative of the machine readable information, and forms an image corresponding to the data in a machine readable code format with the at leas t one fluorescent marking material on an image receiving substrate, and a document reading device including a radiation emitting unit that emits radiation effecting fluorescence of the at least one fluorescent marking material, and a reader that detects the data in the image on the mage receiving substrate while the at least one fluorescent marking material is fluorescing.
