Abstract: An inkjet printing system, comprises an inkjet printer, an ink composition, and an inkjet recording media comprising a support, and coated on the support in order from the support, a porous base layer, a porous intermediate layer, and a porous uppermost layer, each with particular limitations. The inkjet recording media and printer system is manufacturable using low-cost materials in an efficient process requiring only a single coating and drying step and that gives images with excellent gloss, color density and image quality.

Abstract: The invention includes a process for forming a laser pixel array useful with a pump-beam, comprising: a) forming a layer containing a formamide of an amino dye compound on a support wherein the layer absorbs light outside the laser wavelength and predominantly outside the pump-beam wavelength range; and b) subjecting the layer to UV radiation in the areas of the layer where it is desired to be free of pixels for a time sufficient to shift the absorption envelope of the areas into the pump-beam wavelength range. The invention also provides for unimolecularly forming an image or an information record and a composition of matter. The invention provides methods for forming filters, images or information records having a smooth surface and in particular for forming a pixel region pattern for use with an Organic VCSEL that would ease manufacturing.

Abstract: A process for forming an aryl-aryl bond comprises the step of reacting an arene hydrocarbon compound with either (1) an organic oxidant selected from the group consisting of a quinone, a quinone imine, a quinone diimine, and a nitroarene, or (2) an oxidizing salt selected from the group consisting of a triarylaminium salt, an oxonium salt, and a nitrosium salt, or (3) a hypervalent iodine compound, each in the presence of a Brönsted or Lewis acid.

Abstract: The invention provides an ink jet pigment set comprising a magenta pigment, a yellow pigment, and a cyan pigment wherein the normalized spectral transmission density distribution curve of the cyan pigment has a density between 0.66 and 0.94 at 600 nm and a density between 0.83 and 1.0 at 610 nm. Such a pigment set enables an increase in the color gamut obtainable for ink jet imaging.

Abstract: A photographic element containing a dye which when released from a coupler has a sufficiently low pKa, generally less than about 5, such that the dye remains substantially or fully ionized during coating of the film and in the produced film, results in an element containing a dye which has the desired hue without the use of additional additives, such as mordants, to keep the dye ionized. The dye is also useful in photographic elements without release from a coupler, for example, as a filter dye.

Abstract: A stable water soluble epoxy resin suitable for use as a coating material is made by grafting an acid functional vinyl monomer onto unsaturated functional sites on an epoxy resin backbone.
