  • Patent number: 7802881
    Abstract: A water-based ink set for ink-jet recording includes: the infrared absorptive ink that contains the antimony-tin composite oxide fine particles and water; and the color ink that contains the coloring agent and water. The water-based ink set for ink-jet recording is applicable to an ink-jet recording method for recording an image by ejecting the inks onto a recording medium to cause the inks to adhere to the recording medium. When an image having infrared absorptivity is recorded, at least the infrared absorptive ink is ejected onto a recording medium to cause the infrared absorptive ink to adhere to the recording medium.

  • Patent number: 7771037
    Abstract: An ink containing a hydrophobic colloid charged with a positive zeta potential when the pH of the ink is within a range of over 4 and under 6. Silicon or silicon compound can be limited from being eluted into the ink from a circuit board formed from a silicon wafer or the like. Additionally, silicon or silicon compound, if eluted into the ink can be prevented from being deposited on a resistance heater and causing “cogation”, or to prevent the silicon or silicon compound from being deposited in an ink channel and nozzle to clog the nozzle.
