Abstract:
A substantially light-insensitive thermographic recording material comprising a thermosensitive element containing a substantially light-insensitive organic silver salt, a reducing agent therefor in thermal working relationship therewith and a binder, wherein said thermographic recording material contains a compound represented by formula (I) or a reaction product thereof with a polymer having active hydrogen atoms: ##STR5## where R.sup.1 and R.sup.3 independently represent hydrogen, a hydroxyalkyl group, an alkoxyalkyl group, an alkyl group, a --(C.dbd.O)R.sup.5 group or an alkenyl group; and R.sup.2 and R.sup.4 independently represent a hydroxyalkyl group, an alkoxyalkyl group, an alkyl group, a --(C.dbd.O)R.sup.5 group or an alkenyl group; R.sup.5 represents an aryl or an alkyl group; and Z represents the atoms needed to complete a 5 ring-atom or 6 ring-atom hetero-aromatic ring; wherein said compound is exclusively present in said thermosensitive element.
