Abstract
Disclosed is a photothermographic material having an image-forming layer containing a silver salt of an organic acid, photosensitive silver halide grains and a reducing agent on a support, wherein ratio of scratch strength measured before heat development and scratch strength measured 30 minutes after the heat development is in the range of 1:1-1:3 for a surface of the image-forming layer side. The photothermographic material shows improved film strength after heat development.
