摘要:
An emulsion aggregation toner composition includes toner particles including: an amorphous polyester resin; an optional crystalline resin; an optional colorant; an optional wax; an optional coagulant; and a polymeric or oligomeric hydroxy ketone photo initiator capable of initiating crosslinking of said polyester resin, wherein at least one of the amorphous polyester resin and the optional crystalline resin when present is unsaturated.
摘要:
A polyester resin emulsion includes crosslinked polyester resin in an emulsion medium, the crosslinked polyester resin having a degree of crosslinking of from about 0.1 percent to about 100 percent. The emulsion can be formed by solvent flashing a mixture of a polyester resin, an initiator, a solvent, and an emulsion medium, wherein the crosslinked polyester resin has a degree of crosslinking of from about 0.1 percent to about 100 percent.
摘要:
A toner composition comprising a crosslinked resin, a substantially non-crosslinked resin, a was, and a colorant. The crosslinked resin has a crosslinked density of from about 0.3 percent to about 30 percent.
摘要:
An emulsion aggregation toner including a core and a shell wherein the core includes an amorphous polyester, a wax, a crystalline polyester and an optional colorant and wherein the shell includes an amorphous polyester and a wax and is substantially free of crystalline polyester.
摘要:
A light-cyan radiation-curable gel ink including at least one curable monomer, at least one organic gellant, at least one photoinitiator, and a colorant. The colorant includes a cyan colorant, a hue-adjusting colorant that absorbs light having a wavelength of from about 500 to about 600 nm, and an optional shade-adjusting colorant that absorbs light having a wavelength of from about 400 to about 500 nm.
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:
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 toner set includes a plurality of toners, at least one toner but less than all toners of the toner set including binder, colorant and fluorescence agent and remaining additional toners including binder, colorant and free of fluorescence agent. At least a first toner grouping and a second toner grouping of the toner set form a combination, the first and second groupings of the combination exhibiting a substantially same color under ambient light conditions upon image formation. The first toner grouping and the second toner grouping of the combination contain a different amount of the fluorescence agent, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the first toner grouping as compared to the second toner grouping.
