    摘要： Provided is an electrophotographic photoreceptor capable of reducing the rotational torque of the photoreceptor and also reducing the increase in the rotational torque during long-term use when a cured layer obtained by curing a charge transporting compound having a radically polymerizable group is used as a protective layer. In the electrophotographic photoreceptor, a conductive support, a photosensitive layer, and a protective layer are laminated in this order. The protective layer is formed of a cured product of a composition containing the following: a charge transporting compound having a radically polymerizable functional group; and metal oxide particles surface-treated with a surface treating agent having a silicone chain in a side chain thereof.

    摘要： A method for determining coat weight of a printed transparent electrophotographic composition is described, in which a calibration composition is added to a transparent liquid electrophotographic composition to produce a test composition, the calibration composition comprising a carrier liquid, a polymer resin, and at least 5 wt. % of an optical brightening agent based on the total solids content of the calibration composition. The test composition is electrophotographically printed onto a test substrate to produce the printed transparent electrophotographic ink composition; the fluorescence of the printed transparent electrophotographic composition is measured; and the coat weight of the printed transparent electrophotographic composition is determine based on the fluorescence of the printed transparent electrophotographic composition.

    摘要： A digital-printing substrate and method of improving adhesion of a substrate to an liquid electrophotographic (LEP) ink in LEP printing both employ a composite coating. The composite coating includes from 4.5% to 9.5% by weight of a mineral pigment and from 0.5% to 2% by weight of an organic binder uniformly dispersed in water. The mineral pigment has a particle size less than 1 micron. The organic binder comprises a hydroxylated polymer having an average molecular weight greater than 50,000. A weight percentage of hydroxyl groups in the hydroxylated polymer is equal to or greater than a weight percentage of acidic groups in an LEP ink. The composite coating enhances adhesion of the LEP ink to the substrate comprising the composite coating dried on a surface of the substrate.

    摘要： This invention provides hydrophobic compositions for forming hydrophobic toner receptive coatings on a substrate. The hydrophobic coating compositions for forming toner receptive coatings on a substrate contain a hydrophobic polymer comprising: (a) a N-vinyl amide monomer, (b) a non-reactive hydrophobic monomer moiety, and (c) a solvent. The coating compositions may further comprise (d) a substituted or unsubstituted monomer comprising a cyclic ether or an acetoacetate, or mixtures thereof. The invention also provides compositions suitable for addition to toner to enhance adhesion and toner substrates coated with the hydrophobic coating compositions. The hydrophobic polymer may be represented by the following structure, wherein x, y, z, and a, are defined herein.

    摘要： The present invention relates to a reusable print medium comprising a substrate and a sacrificial layer. The sacrificial layer contains a hotmelt composition at least comprising an amorphous material. The amorphous material is a resin being a reaction product of a first monomer A, said first monomer A being a polyhydroxyl alcohol comprising X hydroxyl functional groups, wherein X≧2, monomer A optionally comprises a primary or secondary amine functionality; a second monomer B, being an aromatic monocarboxylic acid; a third monomer C, said third monomer C being able to form an ester linkage with an alcohol and/or an amide linkage with a primary or secondary amine; and optionally, a fourth monomer D, being an aromatic monocarboxylic acid different from the second monomer B. The sacrificial layer including the printed image may be removed from the substrate by applying heat. A new sacrificial layer may be applied such that the reusable print medium is ready to be reused.The present invention also relates to a method of manufacturing a reusable print medium according to the present invention, a method of printing and recycling such a print medium and an apparatus for printing and recycling such a print medium.
