Abstract
A nonpolar or solid (or phase change) ink composition that includes a carrier and at least one nanoscale fluorescent pigment particle composition and/or a fluorescent organic nanoparticle composition. 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.
