    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.
