摘要:
The present disclosure provides carriers for use with toner compositions. In embodiments, a carrier may include a core having a polymeric coating on at least a portion thereof. The polymer coating possesses cation binding groups. Processes for coating such carriers with the polymeric coatings are also provided.
摘要:
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 of a size and charge as to be used as a toner material in electrostatographic or xerographic image formation.
摘要:
A method of predicting a Lewis acid-base relative humidity (RH) ratio in a two-component developer comprised of at least a toner and a carrier including selecting a candidate toner, selecting a candidate carrier, and determining the Lewis acid and Lewis base constants for the candidate toner and candidate carrier. In addition, calculating the Lewis acid-base RH ratio wherein the calculated Lewis acid-base RH ratio is related to charge RH ratio.
摘要:
A toner composition includes core particles including a polymeric latex and an optional colorant, and amino-containing polymer particles dispersed on an external surface of the particles.
摘要:
A toner particle having a core and a shell, and a method for making the toner particle. The core includes a crystalline resin and the shell includes an amorphous resin. The shell is substantially to completely free of the crystalline resin. The toner particle permits inclusion of greater amounts of crystalline resin materials in the core, thereby lowering the minimum fusing temperature of the toner formed from the particles.
摘要:
The present disclosure provides carriers for use with toner compositions. In embodiments, a carrier may include a core, having a dry powder polymer coating. 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.
摘要:
Toner including toner particles having a calcium-containing material at least in a surface portion of the toner particle, wherein the toner particles contain calcium in an amount of from 20 ppm to about 300 ppm of calcium by dry weight of the toner. Developer including a carrier and a toner, wherein the toner includes toner particles having a calcium-containing material at least in a surface portion of the toner particles. In an emulsion aggregation process for making toner particles, the toner particles are treated with calcium. The addition of calcium to the toner particles improves toner performance by lowering cohesion and charging, thereby generating an image of high gloss.
摘要:
A toner process comprising heating a mixture of a latex and a colorant dispersion in the presence of an aggregating agent, and subsequently adding in an amount of at least about 4 weight percent alumina particles, and optionally which particles primarily function as a charge enhancing additive.
摘要:
Carrier comprised of a mixture of a first carrier and a second carrier, and wherein the first carrier is comprised of a steel core and the second carrier is comprised of a magnetite.
摘要:
A carrier comprised of a core and thereover a polymer coating, and which coating is generated by the emulsion polymerization of one or more monomers and a surfactant, and wherein said polymer coating is of a diameter of equal to or less than about 100 nanometers.
