  • Patent number: 7405179
    Abstract: A multicolor thermosensitive recording medium having thermosensitive coloring layers which are formed by printing water-dispersion thermosensitive inks or water-dispersion inks on an ink receptive layer using a printing plate. The recording medium comprises an ink receptive layer formed on a surface of a substrate, thermosensitive coloring layers developing different colors, which are integrated with the ink receptive layer by impregnating the ink receptive layer with a water-dispersion thermosensitive ink that is prepared by dispersing in water a pigment component including at least an electron-accepting compound and electron-donating compound. The color density and coloring sensitivity of the thermosensitive coloring layers have been improved by providing over the thermosensitive coloring layers an auxiliary coloring layer containing at least one of an electron-accepting compound and a sensitizer.

    Abstract: A document sheet issuing system suitable for manufacturing a product based on an ordering by a retailer issues a plurality of documents, e.g., guarantee card, user registration card, on which data including a name of retailer is printed during manufacturing. The issued documents are attached to a carton box in which manufactured product is packed before the product is delivered to thereby reduce troublesome operation by the retailer. The system uses a laminated medium including a lower document sheet and an upper document sheet peelably laminated on the lower sheet. A first data is printed firstly on the lower sheet through the upper sheet and a second data different from the first data is then printed on the upper sheet.

  • Publication number: 20080008963
    Abstract: A reversible heat-sensitive recording medium is provided, which includes a heat-sensitive portion, and a light-transmitting heat-insulating layer disposed to contact the heat-sensitive portion. The heat-sensitive portion contains a light-heat conversion material and a heat-sensitive reversible layer. The light-heat conversion material is enabled to absorb light having a specific wavelength and to convert the light into heat energy. The heat-sensitive reversible layer contains an electron-donating coloring compound and an electron-accepting compound and is enabled to change from a decolorized state to a color-developed state and vice versa, depending on difference in heating temperature and/or cooling temperature to be effected after heating. The light-transmitting heat-insulating is capable of transmitting light having the specific wavelength which the light-heat conversion material is enabled to absorb and also capable of insulating the heat to be emitted from the light-heat conversion material.

    Abstract: A recording apparatus for recording information in a thermosensitive medium which has a photothermal conversion layer having a light wavelength absorption property and a coloring layer colored by the heat generated by the photothermal conversion layer comprises a first light source that emits a light beam for writing information to a scanning position in a main scanning direction in the thermosensitive medium, and a second light source that emits a light of lower energy density than the light beam emitted by the first light source to the scanning position in the main scanning direction in the thermosensitive medium or to the vicinity thereof. The first light source and the second light source emit lights having wavelengths within the range of the absorption property of the photothermal conversion layer respectively to form recording dots of one line in the main scanning direction in a noncontact manner with the thermosensitive medium.

  • Publication number: 20050255235
    Abstract: A thermosensitive recording medium 1 is produced by printing a first water-dispersion thermosensitive ink by a printing method that uses a printing plate on a substrate on a surface of which an ink receptive layer impregnating the first water-dispersion thermosensitive ink is provided, and then printing a second water-dispersion thermosensitive ink using the same printing method. The first water-dispersion thermosensitive ink is prepared by dispersing a pigment that contains at least an electron-donating compound in water, and the second water-dispersion thermosensitive ink contains one or both of at least an electron-accepting compound and a sensitizer that enhances thermosensitive sensitivity. This simplifies a process for manufacturing a thermosensitive recording medium using a printing plate and reduces the manufacturing costs.
