Abstract
The present disclosure relates to a toner design for a clear UV red fluorescence toner having a high lanthanide complex pigment loading, including methods of making the fluorescence toner using a saccharide or a sugar acid to avoid complexation of lanthanide ions from the pigment, with lower aggregation and coalescence temperatures in the preparation of toner particles, where the particles exhibit a narrow size distribution and good xerographic performance.
