A colorless digital primer for digital printing includes a colorless paste. The colorless paste includes a non-polar carrier fluid, and a resin swollen in the non-polar carrier fluid. The resin is present in the paste in an amount ranging from about 20% (w/w) to about 50% (w/w). A solid polar compound is dispersed in the resin. The solid polar compound is selected from the group consisting of a cellulose microcrystalline powder, dextrin, maltose monohydrate, polyacrylic acid, polyvinyl alcohol, a styrene maleic anhydride copolymer, a bismaleimide oligomer, sucrose, sucrose octaacetate, sucrose benzoate, and combinations thereof. The solid polar compound is present in an amount up to 60 wt. % of solids in the colorless paste.

A method of forming an overcoat layer. The method comprises providing a substrate having an imaging structure formed thereon, the imaging structure comprising (i) a charge transport layer and a charge generating layer, or (ii) an imaging layer comprising both charge generating material and charge transport material. An overcoat composition is deposited on the imaging structure, the overcoat composition comprising a charge transport molecule, a fluorinated building block, a leveling agent, a liquid carrier and optionally a first catalyst. The fluorinated building block is a fluorinated alkyl monomer substituted at the α and ω positions with a hydroxyl, carboxyl, carbonyl or aldehyde functional group or the anhydrides of any of those functional groups. The overcoat composition is cured to form an overcoat layer that is a fluorinated structured organic film, the curing comprising treating an outer surface of the overcoat composition with at least one cross-linking process. The crosslinking process forms a cross-linking gradient in the overcoat layer. If the overcoat composition comprises the first catalyst, there is an insufficient amount of the first catalyst to fully cross-link the overcoat layer.

A liquid toner digitally printable media including: a paper substrate; and a toner receiving layer established on at least one surface of the paper substrate. The toner receiving layer includes: pigments, binders, and at least one of cationic polymers and metallic salts. The pigments are from 60 to 95% of total dry weight of the toner receiving layer. The pigments include a major pigment which is at least 60 weight percent of total pigment dry weight. The major pigment includes a rod-like pigment selected from the group consisting of ground calcium carbonate, precipitated calcium carbonate, other rod-like forms of calcium pigment, and combinations thereof.
摘要:
A method for reusing a recording medium forms an image on the recording medium by use of an image forming material, and removes the image forming material from the recording medium through thermal transfer by use of a peeling member. The recording medium is paper produced by applying a treatment liquid at a size pressing after paper making and then drying the treatment liquid. The treatment liquid includes a water-soluble or water-dispersible polymer having an alkyl group with carbon atoms at its side chain as an image-repellant substance. The image forming material includes a thermoplastic resin, and the adhesive strength between the peeling member and the image forming material is higher than the adhesive strength between the recording medium and the image forming material.

An image receiving element is a composite of two or more extruded layers on a support including, in order, an extruded compliant layer, an extruded antistatic tie layer, and an image receiving layer that may also be extruded. The extruded compliant layer is non-voided and comprises from about 10 to about 40 weight % of at least one elastomeric polymer. This image receiving element can be disposed on a support to form a thermal dye transfer receiver element, an electrophotographic image receiver element, or a thermal wax receiver element. Two or more extruded layers can be co-extruded.

摘要:
A recording medium is conveyed through a conveyer path. A recording-medium selecting unit selects either one of a non-transparent recording medium and a transparent recording medium, and conveys a selected recording medium to the conveyer path. An image selecting unit selects an image to be formed on the recording medium from among an original image and a reversed image obtained by reversing the original image. A control unit controls, based on a control signal, the recording-medium selecting unit and the image selecting unit.

An enhanced or optimized cast-coated paper for enhancing or improving toner adhesion, and a method for forming an image on the enhanced or optimized cast-coated paper, includes a paper sheet with a coating solution on at least one surface of the paper sheet, the cast-coated paper having at least: a thermal diffusivity of less than approximately 9.0 mm2/s and total surface free energy component of less than 38 erg/cm2. Printing the cast-coated paper in an electrophotographic apparatus includes forming an image with an electrophotographic toner in the electrophotographic apparatus and transferring the image to the cast-coated paper having the thermal diffusivity of less than approximately 9.0 mm2/s and the total surface free energy component of less than 38 erg/cm2.
