  • Direct thermographic materials with catechol borate reducing agents
    Publication number: 20070015660
    Abstract: Non-photosensitive direct thermographic materials comprise a reducing agent that is a catechol borate compound. These compounds can reduce silver(I) ion to metallic silver to produce a dense black silver image under the short time and high temperature conditions that occur when using thermal print-heads during direct thermal printing.
    Type: Application
    Filed: July 18, 2005
    Publication date: January 18, 2007
    Inventors: Kumars Sakizadeh, Peter Cowdery-Corvan, Leif Olson, David Whitcomb
  • Direct thermographic materials with phenolic reducing agents
    Publication number: 20060128566
    Abstract: Non-photosensitive direct thermographic materials comprise a reducing agent that is a specific ortho-amino-phenol, para-amino-phenol, or hydroquinone compound. These compounds can reduce silver(I) ion to metallic silver to produce a dense black silver image under the short time and high temperature conditions that occur when using thermal print-heads during direct thermal printing. The materials are characterized by their calculated aqueous deprotonation and their calculated anion HOMO energies.
