Abstract: 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.

Abstract: The invention describes a method to control differential gloss of halftone areas produced using substantially clear or low-pigmented toner. It is an objective of this invention to provide a method which allows to produce digital watermarks on paper without being limited in the gloss properties of the toner, the paper or and selected fusing technology. The present invention relates to a method producing clear, low density or highdensity watermarks using Glossmark technology using low-pigmented toner or clear toner. Glossmark technology is for controlling the differential gloss of an image using the steps selecting a first halftone image having a first anisotropic structure, selecting a second halftone image having a second structure different from that of the first halftone, applying the first halftone to at least some portion of the halftone image and applying the second halftone to another portion of the halftone image.

Abstract: Apparatus for bending a receiver having an image side and a non-image side in a bend area having a bend axis. Toner is deposited on the image side of the receiver in the bend area. A device compresses the deposited toner to form a toner film using a heated anvil and a selectively-cooled quencher that stretch and cooled the toner in the bend area below its Tg to form a toner film disposed over the surface of the receiver in the bend area. A heater reheats the bend area of the receiver so that temperature of the toner in the bend area rises above its Tg, so that the toner contracts and the receiver bends at the bend axis.

Such electrographic printing comprises the steps of forming a desired print image, electrographically, on a receiver member utilizing standard size marking particles; and in an area of the formed print image, where desired tactile feel, raised information is to be formed, selectively forming such tactile feel, raised information utilizing marking particles of a substantially larger size than the standard size marking particles of the desired print image.

Abstract: Images produced by electrophotography are often subjected to harsh conditions, such as high temperature and high relative humidity conditions. Prints when subjected to face-to-face stacking under these conditions tend to stick and are difficult to separate without damage. Ethylene-bis-stearamide is incorporated in a protective toner formulation employing a toner binder having a higher glass transition temperature than that of the conventional CYMK colored image toners employed to provide a protective layer in fused images. Further, ethylene-bis-stearamide does not interfere with typical oil release additives used in fuser rollers. By combining ethylene-bis-stearamide with polyalkane waxes having a weight average molecular weight of equal to or greater than 2000 and a poly dispersity of less than 2.0, addition protection can be realized.

Abstract: A receiver having an image side and a non-image side bent in a bend area including a bend axis. Toner is deposited on the image side of the receiver in the bend area using an electrophotographic print engine. The deposited toner is fused to the receiver. During or after fusing, the fused toner is heated to a selected fusing temperature greater than or equal to the Tg of the toner. A heat-shrinkable film is affixed to the heated toner after heating the toner, wherein the Tg of the film is greater than the Tg of the toner. The toner is cooled below its Tg after affixing the film. The bend area of the receiver is reheated after cooling the toner, so that the temperature of the heat-shrinkable film rises above its Tg, the heat-shrinkable film contracts, and the receiver bends at the bend axis.
