Abstract

There is described a novel thermographic recording film, and more specifically, a novel image-forming system incorporated therein which employs both thiolactone and silver reduction chemistries. Thermographic recording films comprising the novel image-forming system of the present invention exhibit excellent thermal sensitivity and visual color saturation, enhanced image density, and desirable visual minimum optical densities.
