    Abstract: A method for reclaiming an out-of-spec emulsion material includes recovering the out-of-spec emulsion material from a scrap manufacturing batch; distilling the out-of-spec emulsion material to raise a solids content of the out-of-spec emulsion material to about 45 wt % or more based on a total weight of the emulsion material; dissolving the distilled emulsion material in a solvent to form a first mixture; adding a base to the first mixture to neutralize acid groups present in the distilled emulsion material, forming a second mixture; emulsifying the second mixture by adding water to the second mixture; and forming particles having an average particle diameter (D50v) within a target range, wherein the out-of-spec emulsion material has an average particle diameter falling outside of the target range.

    Abstract: A phase inversion emulsification process includes dissolving a polyester resin in a mixture comprising (1) an organic solvent, (2) a first portion of a total amount of neutralizing agent, and (3) a first portion of water, neutralizing the dissolved polyester resin with a second portion of neutralizing agent, the second portion of neutralizing agent including the remaining amount of the total amount neutralizing agent, forming an emulsion by adding a second portion of water after the neutralizing step, and removing a portion of the organic solvent from the emulsion to provide a latex.

    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.
