Zusammenfassung:	Thermally developable compositions such thermographic and photothermographic emulsions include certain heterocyclic disulfide compounds and ascorbic acid or reductone reducing agents. These compositions can be used in thermally developable materials such as thermographic and photothermographic materials to provide increased image density and shortened development time, and to allow development at lower temperatures. Such materials can have imaging layers on one or both sides of the support.
