<p>A substantially light-insensitive black and white monosheet thermographic recording material comprising a support and a thermosensitive element containing a substantially light-insensitive organic silver salt, a 1,2-dihydroxyphenyl-compound in thermal working relationship therewith and a binder, characterized in that the 1,2-dihydroxyphenyl-compound is represented by formula (I): <CHEM> where n is 0 or 1; R is -(C=O)R<1>, -(C=O)NR<1>R<2>, -CN, -SO3R<2>, -SO2R<2>, -SOR<2>, -SO2NR<2>R<3> or -PO3R<2>R<3>; R<1> is H or a substituted or unsubstituted alkyl group with 12 or less carbon atoms; and R<2> and R<3> are independently H or an alkyl, a substituted alkyl, an aryl or a substituted aryl group; and R<1> and R<2> together can provide the atoms to close a carbocyclic or heterocyclic ring; and R<2> and R<3> together can represent the atoms to close a carbocyclic or heterocyclic ring; and a recording process therefor.</p> |
