    摘要: The present disclosure relates to a magnetic toner composition. The toner composition includes one or more resins, and spherical ferromagnetic nanoparticles. Also provided is a process for preparing these toners including ferromagnetic nanoparticles. In embodiments, the aggregation of the toner is conducted at a pH greater than about 7, without the use of a coagulant. Additionally, in embodiments, freezing (stopping particle growth) and coalescence of the toner particles may be conducted at a pH greater than about 9. In yet other embodiments, the process may be conducted under an inert gas such as argon to avoid oxidation of the ferromagnetic nanoparticles during toner preparation.

    摘要: Coated phosphorescent pigments are provided which may be utilized in toner compositions. In embodiments, the phosphorescent pigment may be coated by a powder coating process. The large pigment particles may be dry blended with dried resin latex particles, thereby coating the pigment surface, followed by heating and shearing in a rotary kiln or extruder to melt the toner resin and fuse it to the pigment surface. The resulting coated particles may be utilized with other toners, in embodiments color toners, to provide phosphorescent images.

    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.

    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.
