| 20110259238 | AQUEOUS PIGMENT INK - According to one embodiment, an aqueous pigment ink includes water, a pigment, and a water-soluble polymeric compound. The pigment is contained in the aqueous pigment ink in an amount of less than 5 wt %. The aqueous pigment ink has viscosities (mPa·s) measured at 25° C. using a cone-plate type viscometer and satisfying the following relationships: | 10-27-2011 |
| 20110261107 | AQUEOUS INKJET INK - According to one embodiment, an aqueous inkjet ink includes water and a pigment. The pigment is contained in the aqueous inkjet ink in an amount of less than 5 wt %. The queous inkjet ink has viscosities (mPa·s) measured at 25° C. using a cone-plate type viscometer and satisfying the following relationships: | 10-27-2011 |
| 20110273515 | AQUEOUS INKJET INK - According to one embodiment, an aqueous inkjet ink includes a dispersion medium that contains water and a water-soluble polyhydric alcohol having a weight average molecular weight of 400 or more, and a pigment. The pigment accounts for less than 5 mass % of the total amount of the aqueous inkjet ink. The aqueous inkjet ink has viscosities (mPa·s) measured using a cone-plate type viscometer at 20 rpm and satisfying the following relationships: | 11-10-2011 |
| 20110279514 | AQUEOUS INKJET INK - According to one embodiment, an aqueous inkjet ink includes water in an amount of from 15 to 50% by mass of the total amount of the ink, a glycol mixture in an amount of from 34 to 80% by mass of the total amount of the ink, and a pigment in an amount of from 2 to 20% by mass of the total amount of the ink. The glycol mixture contains 40 to 70% by mass of propylene glycol, with the remainder being isoprene glycol. | 11-17-2011 |
| 20110279515 | AQUEOUS INKJET INK - According to one embodiment, an aqueous inkjet ink includes a color material, water as a first liquid, propylene glycol as a second liquid, and a compound represented by the following general formula (PEG) or a compound represented by the following general formula (PGC) as a third liquid. The aqueous inkjet ink has a water activity of 0.85 or less. | 11-17-2011 |
| 20110310140 | INKJET RECORDING APPARATUS AND TREATMENT LIQUID SUPPLY METHOD - This invention provides an inkjet recording apparatus which is provided with a supply unit which supplies a treatment liquid to a recording medium fed from a container and a recording unit which supplies ink to the recording medium with the treatment liquid supplied thereto and forms an image. In the inkjet recording apparatus, the treatment liquid with a first amount per unit area is supplied from the supply unit to a first region of the recording medium, and the treatment liquid with a second amount different from the first amount per unit area is supplied from the supply unit to a second region of the recording medium. The ink with the same amount per unit area is supplied from the recording unit to the first and second regions with the treatment liquid supplied thereto. States of the recording medium and the ink in the first and second regions with the ink supplied thereto are detected, and the supply of the treatment liquid to be supplied to the recording medium is regulated based on the detected states of the recording medium and the ink. | 12-22-2011 |
| 20120013676 | AQUEOUS INKJET INK - According to one embodiment, an aqueous inkjet ink includes a pigment in an amount of 2 to 20% by mass of the total amount of the aqueous inkjet ink, and a dispersion medium in which the pigment is dispersed. The dispersion medium contains water in the amount of 53 to 94% by mass, with the remainder of the dispersion medium being a compound represented by the following general formula 1. The water accounts for 50 to 80% by mass of the total amount of the aqueous inkjet ink. | 01-19-2012 |
| 20120033010 | AQUEOUS INKJET INK - According to one embodiment, an aqueous inkjet ink includes a color material in an amount of 2 to 20% by mass of the total amount of ink, water in an amount of 41 to 70% by mass of the total amount, and a water-soluble organic solvent in an amount of 20 to 53% by mass of the total amount. The solvent contains a compound represented by the following general formula 1 which accounts for 20 to 50% by mass of the total amount of ink. When the amount of compound is equal to the amount of solvent, the total amount of solvent is the compound, and the sum of the amounts of the color material, the water, and the solvent is 100% by mass or less of the ink. | 02-09-2012 |
