Abstract: Toner particles are provided which may, in embodiments, include a core and a shell. In embodiments, charge control agents may be co-emulsified with a resin utilized to form a shell. The shell may prevent a crystalline resin in the core from migrating to the toner surface. Inclusion of the charge control agent in the shell itself may provide the resulting toner particles with desirable charge characteristics and sensitivity to relative humidity.

Abstract: The present disclosure provides toners and processes for preparing toner particles possessing excellent charging characteristics. The process includes forming a dispersion including at least one organic and/or organometallic charge control agent, and then combining that dispersion with an emulsion suitable for use in forming toner particles.

Abstract: 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.

Abstract: A toner including stabilized magnetic single-crystal nanoparticles, wherein the value of the magnetic anisotropy of the magnetic nanoparticles is greater than or equal to 2×104 J/m3. The magnetic nanoparticle may be a ferromagnetic nanoparticle, such as FePt. The toner includes a magnetic material that minimizes the size of the particle, resulting in excellent magnetic pigment dispersion and dispersion stability, particularly in emulsion/aggregation toner processes. The smaller sized magnetic particles of the toner also maintains excellent magnetic properties, thereby reducing the amount of magnetic particle loading required in the toner.

In embodiments, methods of the present disclosure include systems which may be utilized to predict the color properties of a blue toner, thereby permitting adjustment of the pigment loading and/or toner mass per unit area.

Abstract: Toner particles are provided which may, in embodiments, include a high molecular weight branched or cross-linked polyester to decrease image gloss and to increase toner elasticity to prevent surface additives impaction. In embodiments, the toner particles may have a core-shell configuration, with the high molecular weight polyester in the core, the shell, or both.

Abstract: Disclosed herein are methods of using inks with gellants, that can form a gel state, as receivers for particle materials. The inks are liquid when jetted, but quickly enter a tacky/semi-solid/gel state when cooled below ink gel temperature on a substrate and prior to curing. Dry powders and solid particulate substances of various types are then applied to the jetted inks and locked in place when the ink is cured.

Abstract: The present disclosure provides toners and processes for making said toners. In embodiments, the toners include a fluorescent additive having a fluorescent agent. Toners are colorless when viewed under natural light but when exposed to UV light of a specific wavelength the toners are rendered bright green due to the presence of the fluorescent agent.

Abstract: Aspects of the disclosure provide a printing method that can utilize a lightly pigmented toner along with a darkly pigmented toner to improve the image quality. The method can include receiving a dataset corresponding to a printing of a printing system using a darkly pigmented toner. The printing system may have an undesirable optical density printing range for the darkly pigmented toner. Further, the method can include converting the dataset to a first dataset corresponding to a first printing of the printing system using the darkly pigmented toner, and a second dataset corresponding to a second printing of the printing system using a lightly pigmented toner. The first dataset can avoid the undesirable optical density printing range for the darkly pigmented toner, and a combination of the first printing and the second printing providing a substantially same printed optical density corresponding to the received dataset.

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.
