Abstract
Negative-acting photothermographic imaging systems with improved color fidelity and light fastness are disclosed comprising a photobleachable sensitizer, a nitrate salt, an initiator, a leuco dye, a binder, and an optional organic acid. These systems may be used in a variety of applications comprising single or multiple layers in either single or multiple sheet constructions to provide color imaging elements.
