摘要:
An encapsulated toner composition comprised of a core comprised of a monomer, or monomers which are subsequently polymerized; pigment or dye particles; an emulsifier component selected from the group consisting of organic methyl cellulose and hydroxylated methyl cellulose components into which the pigmented monomer mixture is dispersed, and wherein the core is encapsulated within a polymeric shell.
摘要:
An improved process for the preparation of encapsulated toner compositions which comprises mixing core monomer(s), an initiator, or initiators, pigment particles, and oil soluble shell monomer(s); homogenizing the aforementioned mixture into an aqueous surfactant solution resulting in an oil-in-water suspension; thereafter adding water soluble shell monomer(s) to the oil-in-water suspension enabling an interfacial polymerization reaction between the oil soluble and the water soluble shell monomer(s); subsequently adding a low molecular weight polyethylene oxide surfactant protective colloid; and thereafter affecting a free-radical polymerization of the core monomer(s) by heating.

摘要:
A process for the preparation of encapsulated toner compositions which comprises a core dispersion obtained by adding pigment to a monomer, and wherein the pigment is sterically stabilized with a block copolymer; dispersing the resulting core dispersion into an aqueous solution containing an emulsifier; adding thereto an aqueous solution containing a shell monomer; encapsulating the core dispersion by interfacial polymerization of said shell monomer; and heating to initiate a free radical polymerization of the core monomer.
摘要:
A negatively charged toner composition comprised of resin particles, pigment particles, and as a charge enhancing additive certain salts of 5,5'-spirobi(5H-dibenzoborole).

摘要:
A platen cover for an imaging device such as a copier or scanner includes a substrate and at least of portion of the surface of the substrate is coated with a fluorescent coating. Preferably, the substrate has a dark or black color. The dark color of the substrate substantially reduces or eliminates show through of an image on the backside of an original document when the platen cover is not exposed to a light source for imaging. At the same time, when holes or uneven borders are present in the original document, the fluorescent coating fluoresces upon exposure to the light source at these regions of the original document, making these portions appear white in the replicated image and thereby substantially reducing or eliminating the unsightly appearance of these portions as black portions in the replicated image.
