Abstract
Radiation sensitive thermally developable imaging elements comprise: PA1 (a) photosensitive silver halide, PA1 (b) light insensitive silver salt oxidizing agent, PA1 (c) reducing agent for silver ions, and PA1 (d) an antifoggant compound comprising s-triazines having at least one tribromomethyl substituent. The antifoggants are effective in reducing spurious background image densities.
