Abstract: Fluorescent latexes are provided. In embodiments, a fluorescent latex comprises water and fluorescent agent-incorporated resin particles, the particles comprising a resin and a Förster Resonance Energy Transfer (FRET) pair comprising a fluorescent brightener having a fluorescence emission spectrum and a fluorescent dye having an absorption spectrum that overlaps with the fluorescence emission spectrum of the fluorescent brightener, wherein the fluorescent latex exhibits FRET under illumination with ultraviolet (UV) light. Fluorescent toners made from the fluorescent latexes are provided. Methods of making and using the fluorescent toners are also provided.

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: A method for improving z-axis strength of a 3D printed object is disclosed. For example, the method includes printing a three-dimensional (3D) object with a polymer and magnetic particles, heating the 3D object to a temperature at approximately a melting temperature of the polymer, and applying a magnetic field to the 3D object to locally move the magnetic particles in the polymer to generate heat and fuse the polymer around the magnetic particles to improve a z-axis strength of the 3D object.
