Abstract

A photothermographic material contains an organic silver salt, a photosensitive silver halide, a reducing agent, a binder, and a compound of the formula: X--L.sub.1 --D wherein D is an electron donative group of atoms, X is an adsorption promoting group to silver halide, and L.sub.1 is a valence bond or a linking group. It has high sensitivity in the red to infrared region and experiences a minimal change of photographic properties under different developing conditions.
