摘要:
Toners made by the emulsion aggregation process comprising an amorphous resin and a nucleated crystalline resin. Such toners demonstrate improved charging performance in the A-zone and the C-zone, improved heat cohesion and improved resistivity.
摘要:
An improved electrostatic printing method includes printing a first marking material, such as a fully colorized toner, and also printing a second marking material on the same area of the print substrate. The second marking material is a mixture of two toners, where at least one of the two toners has a lower color strength than the first marking material. The second marking material has the same hue as the first marking material, and the ratio of toners in the mixture is such that the second marking material has a color strength matching that of an undesirable optical density printing rage of the first marking material.
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:
Pigment particles with at least one metal oxide surface additive, wherein the at least one metal oxide surface additive is a metal oxide particle covalently bonded with at least one polycondensation polymer, wherein the pigment particle is a pearlescent or metallic pigment.
摘要:
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.
摘要:
A light-magenta solid ink including an ink vehicle and a colorant. The colorant includes a magenta colorant, a hue-adjusting colorant that absorbs light having a wavelength of from about 400 to about 500 nm, and an optional shade-adjusting colorant that absorbs light having a wavelength of from about 600 to about 700 nm.
摘要:
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.
