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.
