20120038703 | INKJET PRINTING APPARATUS AND INKJET PRINTING METHOD - A clear ink layer is formed by a first application of the clear ink. After a film of the clear ink is formed, a second application of the clear ink is performed onto the layer thereof. Thereby, a permeation speed of the clear ink which is applied at the second time after the clear ink is applied once becomes low, and becomes a substantially uniform one in the printed matter. That is, when the clear ink is applied at the second time onto the surface of the clear ink which is once formed into the film, the clear ink permeates therein at a substantially uniform permeation speed and is fixed thereto. As a result, the clear ink which is applied at the second time does not generate unevenness since the permeation speed thereof has no difference thereon, and can form a smooth printed matter surface. | 02-16-2012 |
20120313998 | IMAGE RECORDING METHOD - An image recording method has a feature such that a first ink, a second ink, and a third ink satisfy both the following relationships (1) and (2): (1) the film thickness of dots of the inks formed when one drop of each ink is applied to the recording medium is as follows: First ink>Second ink>Third ink; and (2) the penetration time of the clear ink when applying the inks to the recording medium, and then further applying one drop of the clear ink to the region to which each ink is applied is as follows: First ink≧Second ink≧Third ink. | 12-13-2012 |

20150109365 | INK, INK CARTRIDGE, AND IMAGE-RECORDING METHOD - Provided is an ink containing a self-dispersible pigment, an acrylic resin particle, a surfactant, a water-soluble organic solvent, and water. The surfactant includes a fluorinated surfactant represented by Formula (1) and having an HLB value determined by a Griffin method of 11 or less. The water-soluble organic solvent includes at least one water-soluble organic solvent selected from a specific group, and the total content of the water-soluble organic solvents of the specific group is 4 times or more the total content of the water-soluble organic solvents other than the solvents of the specific group. The total content of the self-dispersible pigment and the acrylic resin particle is 10% by mass or less based on the total mass of the ink. | 04-23-2015 |
20150109384 | INK, INK CARTRIDGE, AND IMAGE-RECORDING METHOD - Provided is an ink containing a self-dispersible pigment, a polyurethane polymer particle, a surfactant, a water-soluble organic solvent, and water. The surfactant includes a fluorinated surfactant represented by Formula (1) and having an HLB value determined by a Griffin method of 11 or less. The water-soluble organic solvent includes at least one water-soluble organic solvent selected from a specific group, and the total content of the water-soluble organic solvents of the specific group is higher than the total content of the water-soluble organic solvents other than the solvents of the specific group. | 04-23-2015 |
20150184007 | INK, INK CARTRIDGE, AND IMAGE-RECORDING METHOD - An ink contains a pigment dispersed with polymer, a surfactant, a water-soluble organic solvent, and water. The mass ratio of a content of the pigment to a content of the polymer in the ink is more than 3. The surfactant includes a fluorinated surfactant which is represented by Formula (1) and which has an HLB of 11 or less as determined by a Griffin method. The water-soluble organic solvent includes at least one selected from specific Group A. The total content of the water-soluble organic solvents of the Group-A in the ink is larger than the total content of water-soluble organic solvents other than the water-soluble organic solvents of Group A in the ink. | 07-02-2015 |
