20130010036 | PRINT HEADS AND PRINT HEAD FLUIDS - Print heads and print head fluids are disclosed. An example print head for an inkjet printer system includes a fluid reservoir, and a nozzle fluidically connected to the fluid reservoir. The example print head also includes a fluid having a liquid vehicle component and a tinting dye. The fluid is provided in the fluid reservoir during shipping of the print head to maintain wetting of the print head. The fluid is discharged after installation of the printer head in the inkjet printer system. | 01-10-2013 |
20130065031 | INK COMPOSITION - Ink composition that includes from about 0.1 to about 10 wt % of metal oxide pigment particles, having an average particle size in the range of about 3 to about 300 nm, that are dispersed with polyether alkoxysilane dispersants; and from about 0.01 to about 3 wt % of water-soluble amphiphilic polymers or of water-dispersible polymer waxes, based on the total weight of the ink composition. Said ink composition forms, onto printable media, a printed feature that exhibits a metallic appearance. Also described herein are the resulting printed article and the method to produce it. | 03-14-2013 |
20130084440 | METALLIC LUSTER PRINTED MEDIUM AND METHOD OF PREPARING SAME - A printed medium having a metallic luster includes an ink-receiving layer on a substrate and a layer of metal oxide particles disposed on the ink-receiving layer. A portion of the ink-receiving layer corresponding to at least one feature includes a non-particulate, light-absorbing colorant dispersed in the ink-receiving layer. An amount of the non-particulate, light-absorbing colorant in the ink-receiving layer portion is sufficient to render a predetermined hue to the metallic luster of the at least one feature. The metal oxide particles have an average diameter of about 3 nm to about 300 nm. The ink-receiving layer has pores that are smaller than the average diameter of the metal oxide particles. | 04-04-2013 |
20130164500 | PRINTED ARTICLE - A printed article with metallic luster and gold-like appearance that encompasses a printable media on which a printed feature has been formed with an ink composition. The ink composition contains iron oxide pigment particles that have an average particle 5 size in the range of about 3 to about 300 nm and the printable media contains a bottom supporting substrate and ink-absorbing layer with pore diameters that are smaller than the average size of the iron oxide pigment particles. In such printed article, the ink composition forms onto the printable media a printed feature that has a thickness that is below about 300 nm. | 06-27-2013 |
20130183500 | PRINTING METHOD - A method for producing printed articles that encompasses providing a first ink composition that contains metal oxide particles with an average particle size in the range of about 3 to about 300 nm; providing a second ink composition that contains non-particulate, light-absorbing colorants dissolved in an ink vehicle; providing a printable media having a bottom supporting substrate and an ink-absorbing layer with pore diameters that are smaller than the size of the metal oxide pigment particles; and applying, on the same print area, the first and the second ink compositions onto said printable media. Also disclosed herein a the printed articles obtained according to the present method. | 07-18-2013 |
20130183501 | PRINTING METHOD - A method for producing printed articles that encompasses providing a first ink composition that contains metal oxide particles with an average particle size in the range of about 3 to about 300 nm; providing a second ink composition that contains colored pigments dispersed in an ink vehicle; providing a printable media having a bottom supporting substrate and an ink-absorbing layer with pore diameters that are smaller than the size of the metal oxide pigment particles and colored pigments; and sequentially applying, on the same print area, the first and the second ink compositions onto said printable media. Also disclosed herein are the printed articles obtained according to the present method. | 07-18-2013 |
20130225748 | WHITE INK COMPOSITIONS - White ink compositions include an aqueous ink vehicle, white pigment particles, and hollow polymer particles comprising a cross-linked polymer shell. An amount of hollow particles in the white ink composition is less than 5% by weight. The white ink compositions have a viscosity of 50 centipoise or less. | 08-29-2013 |
20130284050 | COLORANT DISPERSION FOR AN INK - A colorant dispersion for an ink includes a liquid medium and metal oxide particles dispersed in the liquid medium. The metal oxide particles include a mixture of i) metal oxide particle cores having an organic ligand interacted with respective surfaces thereof, ii) metal oxide particle cores having the organic ligand chemically bonded to respective surfaces thereof, and iii) products of a reaction between metal ions on respective surfaces of metal oxide particle cores and the organic ligand. The organic ligand is chosen from an organic ligand having a phenol group, an organic ligand having a carboxylate group, an organic ligand having an amine group, or combinations thereof. The metal oxide particles exhibit a color that is different from a natural color of the metal oxide particle core. | 10-31-2013 |
20140170384 | NEUTRAL GRAY REFLECTIVE INK - The present disclosure is drawn to an inks, printed articles, and related methods. In one example, the a neutral gray reflective ink can include an aqueous liquid vehicle, iron oxide reflective particles having an average particle size from 3 nm to 180 nm dispersed in the aqueous liquid vehicle, and a dye system solvated in the aqueous liquid vehicle. The iron oxide particles and the dye system are present at relative concentrations to provide a reflective ink that is neutral gray. | 06-19-2014 |
20140352573 | INKJET INK - An inkjet ink includes a pigment incorporated in an aqueous ink vehicle. The pigment includes metal oxide and/or mixed metal oxide particles and a plurality of reacted dispersant molecules attached to the outer surfaces of the particles to form a coating on the outer surfaces. The reacted dispersant molecules are attached to the metal oxide and/or mixed metal oxide particle outer surfaces through a silanol linking group of the reacted dispersant molecules. The coating is present in an amount ranging from about 10 wt % to about 50 wt % with respect to the wt % of the metal oxide and/or mixed metal oxide particles. | 12-04-2014 |
