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: A method for embedding information on a substrate including converting information to machine readable code, wherein the code comprises a set of intended printed markings, wherein each intended printed marking of the set has a predetermined height on a substrate and represents a predetermined value, wherein intended printed markings having a same predetermined height represent a same data value, and wherein intended printed markings representing different data values have different heights; and printing the machine readable code on the substrate by depositing an ultra-violet curable phase change ink comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; a nd a gellant and curing the deposited ink, such that each of the intended print ed markings is formed as a printed marking with the predetermined height.

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: A document includes paper having an average surface roughness of at least about 0.5 microns and including one or more optical brighteners, and include s at least one image thereon wherein the at least one image includes clear binder and light absorbing material that absorbs light only at wavelengths below 350 nm. The image is substantially not detectable to a naked human eye through differential gloss or exposure to light having wavelengths of 365 nm or more, but may be revealed to the naked human eye by exposing the document to light having a wavelength at whi ch the light absorbing material absorbs light.
