Abstract:
The present disclosure relates to a toner including a core comprising at least one amorphous resin, at least one crystalline resin and one or more optional ingredients such as optional colorants, optional waxes, gels, and combinations thereof. The toner also includes a shell having an environmentally friendly charge control agent co-emulsified with at least one amorphous shell resin.
Abstract:
The present disclosure provides carriers for use with toner compositions. In embodiments, a carrier may include a core, having a dry powder polymer coating. The polymer coating possesses a carbon to oxygen from about 3:1 to about 8:1. In embodiments, the coating may also include a colorant, such as carbon black. Processes for coating such carriers with the dry powder polymer coatings are also provided.
Abstract:
Processes for producing emulsion aggregation toners are provided. In embodiments, methods of the present disclosure may be utilized to produce toners suitable for low melt applications, including use in flexible packaging applications, where low pile height is desired for low cost and flexibility. In embodiments, the EA toners may include small particles having a shell with a high amount of resin, which optimizes the charging characteristics of the toner.
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:
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.

An ink 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 ink includes a magnetic material that minimizes the size of the particle, resulting in excellent magnetic pigment dispersion stability, particularly in non-aqueous inkjet inks. The smaller sized magnetic particles of the ink also maintains excellent magnetic properties, thereby reducing the amount of magnetic particle loading required in the ink.

Abstract:
A pigment particle coated with at least one of a resin and a charge control surface additive, wherein the pigment particle is a pearlescent or metallic pigment. The pigment adds pearlescent effects and is a size and charge as to be used as a toner material in electrostatographic image formation.
Abstract:
A custom color toner production system includes a toner delivery system, a cartridge sealing system, a mixing system, and a packaging system. The toner delivery system includes selectively engageable fluid delivery lines for delivering toner of particular color to a cartridge as need for producing a custom color toner in response to an electronically submitted user request. Cartridge containing the unmixed delivered toner may be sealed by a sealing system, and blended using a resonant mixer to produce a custom color toner. The cartridge containing the mixed custom color toner may be packaged using a packaging system.
Abstract:
The disclosure describes a pigment treated with a rosin and a toner particle containing that rosin-treated pigment particle. The toner has a lower level of dielectric loss.
