  • Patent number: 8236192
    Abstract: An ink including stabilized magnetic single-crystal nanoparticles, wherein the value of the magnetic anisotropy of the magnetic nanoparticles is greater than or equal to 2×104 J/m3. The magnetic nanoparticle may be a ferromagnetic nanoparticle, such as FePt. The ink includes a magnetic material that minimizes the size of the particle, resulting in excellent magnetic pigment dispersion stability, particularly in non-aqueous inkjet inks. The smaller sized magnetic particles of the ink also maintains excellent magnetic properties, thereby reducing the amount of magnetic particle loading required in the ink.

  • Patent number: 8083264
    Abstract: A document includes a paper substrate having an average surface roughness of at least about 0.5 microns, wherein the paper substrate includes encoded information printed thereon, and wherein the encoded information is printed with an ink comprised of light absorbing material that absorbs light only at wavelengths below 350 nm and an optional clear binder in a solvent. The encoded information is substantially not detectable to a naked human eye through differential gloss or exposure to light having wavelengths of 365 nm or more, and is only revealed upon exposing the document to light having a wavelength at which the light absorbing material absorbs light, which is less than 350 nm.
