  • Publication number: 20220098374
    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.
