| 20080250967 | DYE DISCHARGING INK FOR INKJET PRINTING - A dye discharging ink for inkjet printing including at least a reducing agent and an amine compound. Embodiments of the dye discharging ink include, as the reducing agent, a sulphur reducing agent such as Rongalite, and, as the amine compound, an alcohol amine compound such as triethanolamine. Embodiments of the dye discharging ink also include a surface active surfactant and/or an antirust agent, and a pH in a range from 9.5 to 11.0. The dye discharging ink for inkjet printing can prevent corrosion of head nozzles due to acidic substances produced by decomposition of a reducing agent, so as to decrease inhibition of linear advancing property of ejected ink, and can prevent decrease in discharging capability due to hydrolysis of the reducing agent. | 10-16-2008 |
| 20080297563 | NOZZLE PLATE FOR INKJET HEAD, METHOD FOR MANUFACTURING THE SAME, AND TREATMENT LIQUID FOR INKJET HEAD - A nozzle plate for an inkjet head including a substrate and ink ejecting holes formed in the substrate. An ink-repellent layer is formed on an ink ejecting side surface of the nozzle plate, and portions of the ink-repellant layer around the ink ejecting holes are selectively removed so that portions of the nozzle plate around the ink ejecting holes are exposed. Also, a method of producing a nozzle plate for an inkjet head is provided that includes preparing a nozzle plate which includes a substrate and ink ejecting holes formed in the substrate and has an ink-repellent layer formed on an ink ejecting side surface of the nozzle plate, and selectively removing portions of the ink-repellant layer around the ink ejecting holes to expose portions of the nozzle plate around the ink ejecting holes. | 12-04-2008 |
| 20090011200 | PRINTING METHOD, PRINTED MATTER, AND PRINTER - A printing method for printing on a washable fabric medium by an inkjet system, where the method includes printing on the medium by the inkjet system using a water-based pigment ink containing an anionic resin. The method further includes applying a water-based coating agent containing water-soluble cationic resin particles to the medium before and/or after the printing on the medium. | 01-08-2009 |
| 20090029049 | ANTIPENETRATING AGENT, SOLVENT INK FOR INKJET PRINTING AND PRINTING METHOD - An antipenetrating agent is to be added to a solvent ink for preventing penetration of the solvent ink into a medium to be printed. The antipenetrating agent includes inorganic fine particles and a resin soluble in an organic solvent. | 01-29-2009 |
| 20090139431 | INKJET INK - A non-water-based inkjet ink containing a colorant, is characterized in that a mixed solvent having a solubility parameter value of from about 8 to about 10 is used as a solvent. The ink is an inkjet ink of which solvent hardly erodes a head member so as to allow long term stable printing and also hardly penetrates the material of media so as to improve the printing quality. | 06-04-2009 |
| 20090139432 | INKJET INK - An inkjet ink containing a colorant, where an amine compound is added as a pH adjuster. The ink is capable of preventing the pH of the ink from being shifted to the acidity side due to corrosive substances (e.g., acid substances) generated by deterioration of ink, adverse effects due to water absorption and moisture absorption, or degradation of resin (e.g., degradation of vinyl chloride-vinyl acetate copolymer resin), thus preventing erosion of a head nozzle member. | 06-04-2009 |
| 20090143509 | INKJET INK - An inkjet ink is provided containing a colorant and using vinyl chloride-vinyl acetate copolymer resin, and characterized in that a stabilizer for preventing the vinyl chloride-vinyl acetate copolymer resin in the inkjet ink from being degraded with age is added. An inkjet ink is provided using VCVAC resin which is capable of preventing the VCVAC resin from being degraded and thus preventing increase in viscosity thereof. | 06-04-2009 |
| 20110104460 | PRINTED MATERIAL AND WATER-BASED COATING AGENT - A printed material includes a cloth medium, a printed layer, and a coating layer. The cloth medium is washable. The printed layer is printed on the cloth medium with a water-based pigment ink including an anionic resin by using an inkjet printing method. The coating layer is provided on at least one of an upper side and a lower side of the printed layer by applying a water-based coating agent including non-ionic water-based resin particles. | 05-05-2011 |
| 20110111187 | PRINTED MATERIAL AND WATER-BASED COATING AGENT - A printed material includes a cloth medium, a printed layer, and a coating layer. The cloth medium is washable. The printed layer is printed on the cloth medium with a water-based pigment ink including an anionic resin by using an inkjet printing method. The coating layer is provided on at least one of an upper side and a lower side of the printed layer by applying a water-based coating agent including anionic water-based resin particles. | 05-12-2011 |
