  • Two-sided thermal paper
    Publication number: 20070207926
    Abstract: Imaging elements for dual-sided direct thermal printing are described, generally comprising a substrate and a thermally sensitive coating on each side. Calendering is provided to produce a smoothness of 75 Bekk or greater on each side of the media product. A subcoat or base coat, e.g., of calcium carbonate or clay, may be provided on paper substrates to enhance smoothness of finish and the quality of thermal printing.

  • Thermal paper with security features
    Publication number: 20060079399
    Abstract: A thermal paper with a fluorescent security mark printed on the thermosensitive coating that is responsive to wavelengths in the range of 200 nanometers to 400 nanometers. The mark is either printed on the thermosensitive coating directly or on an optional protective top coat positioned over the thermosensitive coating. Methods of preparing the thermal paper comprise printing a solution, dispersion or emulsion of a fluorescent compound on the thermal paper by flexographic printing.
