Abstract: Toner particles comprise resin, wax and optionally colorants, and the wax is substantially excluded from the interior core of the toner particles. Processes for preparing such toner particles comprise providing an aqueous dispersion of resin particles and optionally colorants, mixing the aqueous dispersion in presence of a coagulant, aggregating to form particles, coalescing to form fused particles, and removing the fused particles from the aqueous dispersion. Wax dispersions can be added either after mixing or during aggregation, so that wax is excluded from the core of the toner particles.

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.
