Thermally developable emulsions and materials containing heterocyclic disulfide compounds

   
   

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.

Le composizioni termicamente developable tali emulsioni termografiche e photothermographic includono determinati residui eterociclici del bisolfuro e l'acido ascorbico o gli agenti riduttori del reduttone. Queste composizioni possono essere usate in materiali termicamente developable quali i materiali termografici e photothermographic per fornire la densità di immagine aumentata ed il tempo di sviluppo ridotto e per permettere lo sviluppo alle temperature più insufficienti. Tali materiali possono avere strati di formazione immagine da un o entrambe il lato del supporto.
