Abstract

A thermographic dye transfer image-recording material is provided wherein a particular silver salt complex is employed as a source of silver ions, made available upon imagewise heating, to cleave a dye-providing material to provide a diffusible dye in an imagewise pattern corresponding to said imagewise heating. The silver salt complexes have improved solubility in the system providing for enhanced transferred image density.
