Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim herein: 1. A UV red fluorescent toner comprising a pigment comprising a lanthanide complex in an amount of at least about 3 wt %, at least one amorphous resin, an optional crystalline resin, an aggregating agent, a stabilizer that does not chelate metal ions, wherein the stabilizer comprises a salt of gluconic acid selected from sodium gluconate or potassium gluconate, optionally a surfactant and optionally a wax, wherein the toner exhibits an absorption λ max of between…
