    Abstract: Fluorescent green toners are provided. In embodiments, a fluorescent green toner comprises fluorescent agent-incorporated resin particles comprising a resin, a fluorescence brightener, and a yellow fluorescent agent having an absorption spectrum that overlaps with a fluorescence emission spectrum of the fluorescence brightener; and a cyan colorant; blue dye-incorporated resin particles comprising the resin and a blue dye; or both. The fluorescent green toner has a weight ratio of the yellow fluorescent agent to the cyan colorant and, if present, the blue dye, in a range of from 100:1 to 0.2:1, and the fluorescent green toner exhibits Førster Resonance Energy Transfer (FRET) under illumination with UV light. Methods of making and using the fluorescent green toners are also provided.

    Abstract: Methods of making fluorescent pink toners are provided which comprise forming one or more fluorescent latexes which comprise a red fluorescent agent, a yellow fluorescent agent, a first type of amorphous resin, and a second type of amorphous resin, wherein the first and second types of amorphous resins are present at a ratio in a range of from 2:3 to 3:2; forming a mixture comprising the one or more fluorescent latexes; one or more emulsions which comprise a crystalline resin, the first type of amorphous resin, the second type of amorphous resin; and optionally, a wax dispersion; aggregating the mixture to form particles of a predetermined size; forming a shell over the particles of the predetermined size to form core-shell particles; and coalescing the core-shell particles to form a fluorescent pink toner. Fluorescent pink toners and methods of using such toners are also provided.

    Abstract: A method for forming a dispersion includes mixing graphene particles, a fluorosilane coupling agent and a first solvent to produce a first dispersion wherein the graphene particles are from about 0.1 to about 0.8 weight percent of the first dispersion. The method includes concentrating the first dispersion by removing the first solvent to produce a second dispersion wherein the graphene particles are from about 2.0 to about 10.0 weight percent of the concentrated dispersion. The concentrated dispersion is mixed with a fluoropolymer dispersion including a second solvent, a surfactant, and fluoropolymer particles wherein the fluoropolymer dispersion has a solids content of about 30 weight percent to about 50 weight percent to form a second dispersion. A polymer binder in a third solvent is mixed with the second dispersion to form the coating dispersion.
