Abstract: An aluminum chelate, a method for manufacturing the same and a photo cured ink including the same are revealed. First rosin resin is modified by epoxy and acrylic acid to get acrylic acid modified rosin resin. Then an aluminum chelating agent undergoes a chelation reaction with the acrylic acid modified rosin resin to form a plastic fluid whose chemical structure contains a photoreactive group and a chelate structure with aluminum. The plastic fluid can be added into photo cured inks so that the photo cured inks have better ink tack, ink flow, color density and stability.

Abstract: A method of increasing color gamut of a color display includes grouping subpixels of R, G, and B primary colors of a pixel by grouping R, G, and B light sources of the color display with a corresponding light intensity adjustment mechanism based on an overlapping degree between two response spectrums of the light sources. The response spectrums of the light intensity adjustment mechanism of the same group have minimal overlapping with that of other groups. The method further includes enabling groups of R, G, and B subpixels, activating the R, G, and B light sources and the corresponding light intensity adjustment mechanism, and disabling the remaining groups of subpixels all by turns for creating a vivid complete picture by time division color-mixing.

Abstract: A multicolor ink jet printing process employs an ink jet ink composition comprising water, a colorant of pigment, dye, or mixtures thereof, and a low boiling point additive to produce high quality multicolor ink jet images with minimal intercolor bleed and lines with sharp edges as characterized by a relatively low mid frequency line edge noise (MFLEN) number. The additive is an alcohol or thiol having a boiling point less than or equal to about 115° C. The aforementioned ink jet ink composition can further include an optional additive of alcohol or thiol with a boiling point less than or equal to about 135° C. if necessary. The desired additive increases the ink's drying rate with fast evaporation and an accelerated penetration into a print substrate (e.g. paper) upon printing. As a result, little or minimum residual ink (e.g. carbon black ink) comprising the aforementioned additive is available on the surface of the print substrate to intermix with a previously or subsequently printed ink (e.g.

Abstract: The present invention relates to aqueous ink jet ink compositions comprising an anti-intercolor bleed agent, preferably a water soluble or ink-compatible agent. The inks typically also comprise water and at least a colorant of a dye, a pigment, or a mixture of dye and pigment. In one embodiment, ink jet ink compositions comprising an anti-intercolor bleed agent which is represented by {[(R)m—G)b]n}s(A)(X)p (Formula (I)), and ink jet printing processes which print the ink jet ink compositions in any desired printing sequence or order onto an optionally heated substrate are provided. The water-soluble or ink-compatible anti-intercolor bleed agent may form hydrophobic layers near the image boundary, thus preventing undesired mixing of two different neighboring inks which forms intercolor bleed. The ink jet ink compositions of the present invention exhibit reduced drying time, intercolor bleeding, and image defect as well as providing uniform ink images on transparencies.

The aqueous ink jet ink possesses a latency of at least 10 seconds at a relative humidity of 15% in either a high resolution (>360 spi) printhead or full-width array printhead having at least one nozzle opening of a diameter or size ranging from 10 to about 49 microns.

Abstract: The present invention relates to aqueous ink jet ink compositions comprising a water-soluble or ink-compatible anti-intercolor bleed agent. The ink jet ink compositions typically comprise water, a colorant of dye or pigment, or a mixture of dye and pigment, and a water-soluble or ink-compatible anti-intercolor bleed agent. In one embodiment the water-soluble or ink-compatible intercolor bleed agents of the invention comprise glycine materials with or without a fluorine atom and are represented by formula (I) in either ionic or nonionic forms, particularly those of fluorinated glycine salts with high fluorine content. The water-soluble or ink-compatible anti-intercolor bleed agent in an ink jet composition is believed to accelerate ink drying and to form hydrophobic layers on a print substrate near the image boundary in an ink jet printing process, thus minimizing undesired mixing of different neighboring inks resulting in a reduction of intercolor bleed.
