  • Nanoparticle based inks and methods of making the same
    Publication number: 20090169745
    Abstract: The present invention provides nanoparticle based recording mediums, inks and ink compositions, methods of making nanoparticle based recording mediums and inks, nanoparticles and methods for making nanoparticles, methods for stabilizing colorants against electromagnetic radiation (including radiation in the visible wavelength range), methods for enhancing the substrate independent durability performance of inks, and methods for color density control. The nanoparticle based inks deliver better color, color density control, improved printability, enhanced durability, and increased lightfastness, and are capable of being printed on woven and non-woven fabrics and paper products without special treatment or other limitations.

  • Recording medium with nanoparticles and methods of making the same
    Patent number: 7030176
    Abstract: The present invention provides recording media comprising nanoparticles, methods of stabilizing recording media against electromagnetic radiation (including ultraviolet radiation and radiation in the visible wavelength range), methods for enhancing the substrate independent durability performance of recording media, and methods for color density and hue control. The recording media deliver improved color, better color density control, improved printability, enhanced durability, and increased lightfastness, but also are capable of being printed on all substrates including woven and non-woven fabrics and paper products, without special treatment or other limitations.
