New heat-sensitive irreversible colour former derived from aromatic isocyanates and imino compounds

Kazuo Kabashima; Migaku Tanaka; Shigetoshi Hiraishi; Masaru Matsuoka

Abstract New heat-sensitive irreversible colour former systems were first developed by the reaction of aromatic isocyanates with imino compounds. This colour developing reaction is irreversible to give pigment type chromophores, and then provides an excellent colour image with good chemical and light stabilities. The colour images can be controlled from yellow to brownish black by changing combinations of each component.
