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.

Abstract: Methods of making a crosslinked fluorescent latex are provided. In an embodiment, such a method comprises adding a water-soluble initiator to an uncrosslinked fluorescent latex comprising water and uncrosslinked resin particles comprising an unsaturated resin and a fluorescent agent incorporated therein; and exposing the water-soluble initiator to conditions to activate the water-soluble initiator and induce crosslinking reactions between the activated water-soluble initiator and the unsaturated resin, thereby forming a crosslinked fluorescent latex comprising crosslinked fluorescent resin particles comprising crosslinked resin and the fluorescent agent incorporated therein. Crosslinked fluorescent latexes are also provided, as are fluorescent toners made from the same.

Abstract: Methods of making fluorescent metallic toners are provided which comprise forming one or more fluorescent latexes which comprise a 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; a dispersion comprising aluminum flakes and a surfactant; 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 metallic toner. Fluorescent metallic toners and methods of using such toners are also provided.

Abstract: A toner process comprising (a) providing at least one amphiphilic block copolymer prepared by surfactant-free emulsion polymerization comprising: dissolving a hydrophilic monomer in water; adding a hydrophobic monomer; adding a feed initiator to produce a colloidal dispersion of amphiphilic block copolymer; and optionally, discharging the amphiphilic block copolymer; (b) contacting one or more of a latex polymer, a wax; and a colorant with the colloidal dispersion of amphiphilic block copolymer to form a blend; or contacting the discharged amphiphilic block copolymer with one or more of a latex polymer, a wax dispersion, and a colorant dispersion, and forming a further dispersion; (c) heating the blend or further dispersion at a temperature below the glass transition temperature of the latex polymer to form aggregated toner particles; (d) adding a coalescing agent to the toner particles thereby coalescing the toner particles; and (e) recovering the toner particles.
