摘要： A method is described for the preparation of electrostatographic toner particles which involves the surface treatment of a pigment by depositing thereon a coating of an elastomeric thermoplastic polymer. The method involves preparing a polymer solution by dissolving an elastomeric thermoplastic polymer selected from the group consisting of linear styrene-isoprene-styrene triblock copolymers, linear styrene-ethylene-butylene-styrene triblock copolymers, linear styrene-isoprene diblock copolymers and linear styrene-ethylene-propylene diblock copolymers in a first solvent capable of dissolving the polymer at ambient temperature; forming a pigment dispersion by mixing at ambient temperature a pigment, a first polymer material and a second solvent in which the elastomeric thermoplastic polymer is insoluble at ambient temperature; admixing the polymer solution with the pigment dispersion so resulting in the elastomeric thermoplastic polymer precipitating out upon the surface of the pigment; mixing the elastomeric thermoplastic polymer coated pigment dispersion thus formed with a solvent in which the elastomeric thermoplastic polymer is insoluble at ambient temperature and, optionally, a second polymer material and, optionally, a charge-control agent to form an organic phase; dispersing the organic phase in an aqueous phase comprising a particulate stabilizer and, optionally, a promoter; homogenizing the resultant mixture, and evaporating the solvent and washing and drying the resultant product.

摘要： A fluorescing dry toner particle comprises a polymeric binder phase comprising a non-fluorescing binder polymer and a polymeric fluorescing colorant dispersed within the non-fluorescing binder polymer. The polymeric fluorescing colorant comprises a fluorescing moiety that is covalently attached to a colorant polymer that is the same or different than the non-fluorescing binder polymer, but the polymeric fluorescing colorant is blendable with the non-fluorescing binder polymer to form a homogeneous polymeric binder matrix, and is present in an amount of at least 1 weight % and up to and including 40 weight %, based on the total fluorescing dry toner particle weight. These fluorescing dry toner particles can be used in various dry developers to provide fluorescing toner images with or without non-fluorescing color toner images.

摘要： A method for determining color separation image data for printing for an ink jet printer. Target colors are determined as a function of location in accordance with the image data, and color separation image data is determined specifying amounts of a fluorescent ink and one or more non-fluorescent reflective inks to be combined to form the target colors when printed on an ink receiver. For target colors having a specified hue angle the amount of the fluorescent ink is decreased as a density of the target color increases beyond a threshold density level.

摘要： A composite color toner image can be enhanced in a printed receiver material by having a separate fluorescing magenta toner image applied over it to provide a “pinkish” fluorescing effect. This separate fluorescing magenta toner image is obtained using visible fluorescing dry magenta toner particles, each of which has a polymeric binder phase and a visible fluorescing colorant that emits at one or more peak wavelengths of from 510 nm and to and including 590 nm. The covering power of the fused visible fluorescing magenta toner particles in the enhanced composite color toner image is at least 350 cm2/g to and including 1100 cm2/g, and the covering power of each of the non-fluorescing cyan, non-fluorescing yellow, non-fluorescing magenta, and non-fluorescing black toner particles in the enhanced composite color toner image is at least 1500 cm2/g to and including 2300 cm2/g.

摘要： A method for producing a raised print on a receiver includes receiving image data and height data. The height data specify that raised printing should be produced in non-first-color region of the image data. Separation data are determined for a clear toner, a light toner having the first color, and at least two additional colored toners. The separation data for the clear toner is determined in response to the height data and the separation data for the light toner is determined in response to the image data and the height data so that the clear and light-toner separations specify that respective toners be deposited one atop the other in the non-first-color region. Respective toner images are deposited on the receiver, each corresponding to respective separation data. The deposited toner is fixed to the receiver member.
