Abstract
Fluorescent orange latexes are provided which comprise water and fluorescent agent-incorporated resin particles, the particles comprising a resin, Solvent Red 49 as a red fluorescent agent, and Solvent Yellow 98 as a yellow fluorescent agent, wherein the fluorescent orange latex has a weight ratio of the Solvent Yellow 98 to the Solvent Red 49 in a range of from 20:1 to 0.5:1. Fluorescent orange toners and methods of making and using the fluorescent orange toners are also provided.
Claims20
A fluorescent orange toner comprising toner particles, the toner particles comprising fluorescent agent-incorporated resin particles comprising a resin, Solvent Red 49 as a red fluorescent agent, and Solvent Yellow 98 as a yellow fluorescent agent, and a fluorescent brightener having a fluorescence emission spectrum that overlaps with an absorption spectrum of the yellow fluorescent agent, wherein the fluorescent agent-incorporated resin particles have a weight ratio of the Solvent Yellow 98 to the Solvent Red 49 in a range of from 20:1 to 0.5:1, and wherein the fluorescent orange toner exhibits Förster Resonance Energy Transfer (FRET) under illumination with light having a wavelength to excite the yellow fluorescent agent and FRET under illumination with ultraviolet light.
