| 20090246479 | Ink-jet recording water-based ink composition - An ink-jet recording water-based ink composition includes a polymer obtained by emulsion polymerization of a monomer having an ethylene-type unsaturated bond in the molecule and divinylbenzene in the presence of a reactive emulsifier, a polyethylene-based wax, a water-soluble resin, water, and a colorant. When ink coat is formed on a plastic film having a degree of gloss at 60° of 140 to 150 by discharging droplets of the ink composition onto the plastic film, the ink coat has a degree of gloss at 60° within a range of 50 to 120. | 10-01-2009 |
| 20090295847 | PRINTING METHOD USING INKJET RECORDING METHOD AND PRINTING APPARATUS - [Problems] There is provided a printing method using an inkjet recording method for printing on non-ink-absorptive and low-ink-absorption recording media that is excellent in terms of image quality, resistance to abrasion, and discharge stability no matter how ink-absorptive recording media used therewith are. | 12-03-2009 |
| 20100086691 | PRINTING METHOD EMPLOYING INK JET RECORDING TECHNIQUE - A printing method employing an ink jet recording technique includes: forming an image with an ink jet recording technique by ejecting droplets of a water-based ink composition onto a recording medium having no or low ink absorbency; and drying the water-based ink composition on the recording medium, the drying being conducted so as to at least overlap the forming. The water-based ink composition contains at least one selected from N-methyl-2-pyrrolidone, tetramethylurea, and dimethyl sulfoxide; a water-insoluble coloring agent; a water-soluble resin; thermoplastic resin particles; a silicone-based surfactant; an acetylene glycol-based surfactant; a penetrating agent; a moisture retaining agent; and water. The total content of the N-methyl-2-pyrrolidone, the tetramethylurea, and the dimethyl sulfoxide in the water-based ink composition is 3.0 to 10.0 mass %. The content of the penetrating agent in the water-based ink composition is 3.0 to 8.0 mass %. The content of the moisture retaining agent in the water-based ink composition is 5.0 to 10.0 mass %. | 04-08-2010 |
