摘要:
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.

The present disclosure provides white toner compositions and processes for making same. In embodiments, a desirable white toner may be produced without having to resort to excessive pigment loading, having desirable gloss characteristics.
摘要:
Disclosed herein are curable solid inks which are solid at room temperature and molten at an elevated temperature at which the molten ink is applied to a substrate. In particular, the curable solid inks of the present embodiments comprise low molecular weight amide gellants that impart self-leveling capabilities to the inks. Also disclosed herein are methods for making the amide gellant and the inks comprising the amide gellants.
摘要:
A solid ink composition suitable for ink jet printing, including printing on coated paper substrates. In particular, the solid ink composition comprises a crystalline compound, an amorphous compound, and an inorganic nucleating agent, which provides for a robust and fast printing ink.
摘要:
A process for making toner particles is provided. In embodiments, a suitable process includes adding a defoamer to an emulsion utilized to form toner particles. Utilization of the defoamer allows for a reduction in the overall aggregation/coalescence cycle time and slurry viscosity, while producing a toner with improved GSDs, low coarse and target circularities.
摘要:
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 additive that renders them visible when exposed to UV light of a specific wavelength. By selecting the appropriate UV additive and ionic crosslinker, with optional chelating agent, 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.
摘要:
A fluorescent particle includes a fluorescent pigment, such as a trans-dicarboxylic-indenofluorenone, and at least one stabilizing wax chemically attached to the fluorescent pigment. The stabilizing wax includes an amine group at its terminal end and the fluorescent pigment includes at least one carboxylic acid group, where the amine group reacts with the carboxylic acid group to form an amide bond. A method for making fluorescent particles for use in toners by chemically attaching at least one stabilizing wax to a fluorescent pigment where the at least one stabilizing wax includes an amine group at its terminal end and the fluorescent pigment includes at least one carboxylic acid group. A toner may include a resin and the fluorescent particle.
摘要:
The present disclosure provides toner particles having excellent charge characteristics. In embodiments, a toner particle of the present disclosure includes a cation binding material possessing cation binding groups. Processes for producing toners with these cation binding materials are also provided. The resulting toners exhibit excellent stability with respect to relative humidity and excellent charging characteristics.
摘要:
Fluorescent organic nanoparticles and a process for producing fluorescent organic nanoparticles having a size of less than about 500 nanometers comprising a polymeric matrix comprising one or more crosslinked polymer resins, and comprising one or more fluorescent dyes incorporated into the polymer matrix.
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.
