Abstract: Toner compositions of toner particles including additive particles upon an external surface of the toner particles, wherein the additive particles include crosslinked styrene containing polymer particles, exhibit reduced sensitivity to relative humidity. The crosslinked styrene containing polymer particles have an average particle size of from about 30 nm to about 300 nm, and may include styrene homopolymer particles, styrene copolymer particles or mixtures thereof. A process of reducing the relative humidity sensitivity of toner using such external surface additive is also described.

Abstract: The present disclosure provides processes for producing images of excellent color fidelity when incorporating a magenta toner with a lower colorant loading in addition to a first magenta toner. In embodiments, the magenta pigmented particles may be magenta emulsion aggregation toners. In accordance with the present disclosure, a pair of magenta toners are matched in color, wherein the color of a first magenta toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second magenta toner, which is lighter than the first magenta toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable. In embodiments, the light magenta toner is color matched by adding a hue-adjusting colorant or combination of colorants which absorb wavelengths of light between 400 and 500 nanometers, and optionally adding a shade-adjusting colorant or combination of colorants which absorb wavelengths of light between 600 and 700 nanometers.

Abstract: The present disclosure provides toners and processes for making said toners. In embodiments, the toners are invisible when viewed under natural light, but possess a UV emitter that renders them visible when exposed to UV light of a specific wavelength. By selecting the appropriate UV emitter and utilizing an ionic crosslinker, the gloss of the toner may be tailored to match the gloss of any substrate, such as paper, to which the toner is to be applied, thereby further enhancing its invisibility under visible light.
