摘要:
This invention provides a gloss-coated electrophotographic paper with superior runnability and print quality in colour and monochrome copiers and printers. The coated paper product comprises a paper substrate coated on at least one side with a pigmented coating. The pigment coating consists of a mixture of at least three different pigments and a binder. The coating may further include a lubricant. Optionally, the coating formulation may contain an optical brightening agent, a defoamer and a thickener. In addition, the gloss coated electrophotographic paper of this invention provides a superior toner adhesion in colour and monochrome electrophotographic imaging applications.
摘要:
The invention relates to a gloss coated multifunctional printing paper that can be used with a variety of office printing equipment including inkjet and electrophotographic and to processes of making and using the paper. a paper substrate; and a pigmented composition coated on at least one surface of the substrate, said pigmented coating composition comprising (1) a first pigment having a BET surface area in the range of from about 50 to about 750 m2/g,; (2) a second pigment having a BET surface area in the range of from about 5 to about 49 m2/g; and (3) a polymeric binder, Said coated paper having a coating gloss equal to or greater than about 30% at 75° and a Bristow Absorption length of less than about 180 mm. The coating compositions may contain other additives such as lubricants, optical brighteners and coating rheology modifiers. The coating formulations can be applied to the base stock using any of a large number of coating techniques including application roll with bent blade, rod, air knife, slot die, curtain spray and gravure. The paper can be used with various inkjet and electrophotographic printing apparatus and techniques.
摘要:
The present invention relates to a sizing composition that, when applied to paper substrate, creates a substrate, preferably suitable for inkjet printing, having increased print density, print sharpness, low HST, and/or image dry time, the substrate preferably having high brightness and reduced color-to-color bleed as well. In addition, the present invention relates to a method of reducing the HST of a paper substrate by applying the sizing composition to at least one surface thereof. Further, the application relates to methods of making and using the sizing composition, as well as methods of making and using the paper containing the sizing composition.
摘要:
A process comprising treating a lignocellulosic material preferably pulp in the presence of a transition metal catalyst with a oxidizing agent selected from a group consisting of hydrogen peroxide, hypochlorite, hypochlorous acid and any combination thereof to form a treated lignocellulosic material having a viscosity equal to or less than about 17 cp and having reducing functional groups selected from the group consisting of aldehyde and aldehyde type functional groups at the C6 and C1 positions but predominating at the C1 position.
摘要:
A method performed by a processor of a electronic device, including rendering (402), on an electronic display, a line segment having a first direction and moving in a second direction. The method also includes a step of determining (404) whether the direction of the line segment (the first direction) is in the same direction that the line segment is moving (the second direction). If the processor determines that the line segment is not moving in the same direction of the direction of the line segment (the first direction), then the processor performs (408) a first action, such as adjusting the color intensity of the line segment. If the processor determines that the line segment is moving in the same direction of the direction of the line segment (e.g., the two directions are substantially parallel to each other), then the processor performs (406) a second action.

摘要:
An article in the form of a paper substrate having a first surface and a second surface; an internal paper sizing agent present in an amount sufficient to impart to the paper substrate an HST value of from about 50 to about 250 seconds; and a metal salt drying agent having at least about 20% by weight of one or more monovalent metal drying salts, wherein the metal salt drying agent is present on at least one of the first and second surfaces in an amount sufficient to provide a percent ink transferred (“IT %”) value equal to or less than about 65% and to provide a black print density value of at least about 1.45. Also, a method for treating the internally sized paper substrate having the HST value of from about 50 to about 250 seconds with the metal salt drying agent.
摘要:
Compositions and methods are disclosed for preventing or reducing frizzy appearance of keratin fibers, including hair, and reducing the amount of fly-away strands of hair, particularly in humid conditions, by forming a coating on hair that is resistant to water vapors from the air or surrounding environment. The compositions comprise a combination of a hydrophobic particulate material comprising a hydrophobically surface-modified aluminum oxide and one or more hydrophobic film formers in a cosmetically acceptable vehicle.

A camera-movement compensation device includes a first liquid-crystal cell with a pair of parallel transparent plates and a first voltage source coupled to the first liquid-crystal cell and able to apply and alter a first voltage gradient across the plates of the first liquid-crystal cell. The device also includes a second liquid-crystal cell having a pair of parallel transparent plates and disposed so that each of the plates of the second liquid-crystal cell is parallel to the plates of the first liquid-crystal cell and in light communication with at least one wave of light passing through the plates of the first liquid-crystal cell, a second voltage source coupled to the second liquid-crystal cell and able to apply and alter a second voltage gradient across the surfaces of the second liquid-crystal cell, and a movement detector coupled to the voltage sources to alter the slope of the voltage gradients in proportion to a movement.
