    摘要: Process for passivating polymeric particles to prevent undesirable interaction with the environment. In particular, sputter coating of metal and surface treatment with aqueous solutions are shown to successfully passivate the particles, such as for example, toner particles, and prevent interaction between the particles and the epoxy embedding resin which causes artifacts, observed by transmission electron microscopy (TEM) imaging.

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

    摘要: Processes for producing toners are provided. The processes include determining the desired gloss for a given toner, and determining the desired amount of aluminum in the toner to obtain that gloss. Utilizing the processes of the present disclosure, the solids content of an emulsion utilized to produce such a toner, as well as the mixing speed utilized in the aggregation process and the temperature at which aggregation of the toner particles occurs, may then be selected to obtain toner particles possessing the desired amount of aluminum, and thus the desired gloss.

    摘要: 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.
