Abstract
An emissive toner composition for producing an emissive image component of an image indicia on a substrate. The emissive toner composition includes a photoluminescent agent, a charge control agent, and one or more additives, each selected and present in an amount such that when the toner composition is printed to produce an image component on a substrate, the toner composition has stable spectral characteristics. In one embodiment, the emission spectra of the image component printed on the substrate, for irradiation with an excitation energy includes only dominant emission peaks corresponding to one or more emission peaks of the photoluminescent agent. In another embodiment, the image component has a photoluminescent toner stability factor of about greater than or equal to 25.
