  • Patent number: 7192474
    Abstract: Water-soluble, photosensitive, optically variable (POV) inks exhibit improved OCR readability due to improved infrared absorption properties. The inks can produce images that can be viewed with both visible and ultraviolet light to have physically coincident positive and negative images. The new inks contain at least two types of colorants in addition to the IR absorber and other suitable ingredients. The first colorant comprises a fluorescent dye or pigment emitting light within a characteristic emission band when excited by fluorescent-exciting radiation. The second colorant comprises a carbon black infrared radiation absorbing composition alone or with one or more dyes or pigments having a light absorption band at longer wavelengths than the characteristic emission band of the first colorant or also overlapping the emission wavelength of the first colorant in such a way as to result in a dark color.

  • Patent number: 7192476
    Abstract: A fluorescent water base ink for ink-jet recording contains a fluorescent dye having a xanthene skeleton, and a glycol. In the fluorescent dye, the difference in hydrophilic index log P is not less than 2.6 between a substituent bonded to C-9 carbon atom of the xanthene skeleton and other portion of the fluorescent dye than the substituent bonded to the C-9 carbon atom. The glycol has a distance between hydroxyl groups substantially equivalent to or longer than an interatomic distance between atoms directly bonded to C-3 and C-6 carbon atoms of the xanthene skeleton of the fluorescent dye, respectively. It is assumed that the glycol is coordinated with the xanthene skeleton in a bridge form to increase the fluorescence intensity by increasing the electron density of the xanthene skeleton. The ink having high fluorescence intensity and in which the fluorescence intensity is not lowered in a time-dependent manner is provided.
