Abstract: A black and white monosheet thermographic recording material comprising a support and a thermosensitive element, the thermosensitive element containing a substantially light-insensitive organic silver salt, an organic reducing agent therefor in thermal working relationship therewith, a binder and at least one toning agent, wherein the at least one toning agent is represented by formula (I): 1 wherein R1 is a hydrogen atom or an alkyl, an alkenyl, an alkynyl, a cycloalkyl, an alkaryl, an aryl, a heterocyclic or a heteroaryl group all of which may be optionally substituted; with the proviso is that R1 may not be a hydrogen atom if both R2 and R3 are both hydrogen atoms; R2 and R3 are independently a hydrogen or a halogen atom or an amino, amide, ester, carboxy, carbonate, alkyl, alkenyl, alkynyl, cycloalkyl, alkaryl, aryl, heterocyclic or heteroaryl group all of which may be optionally substituted; R2 and R3 may together represent the atoms necessary to complete a heteroaromatic ring with no more than one nitrogen atom, an alicyclic or a heterocyclic group which all may be optionally substituted; and X is a carbonyl group, or is nullNnullR4, where R4 is an alkyl group.

Abstract: A black and white monosheet substantially light-insensitive thermographic recording material comprising a support and a thermosensitive element, the thermosensitive element containing a substantially light-insensitive organic silver salt, an organic reducing agent therefor in thermal working relationship therewith, a binder and at least one toning agent, wherein the at least one toning agent is selected from compounds represented by formula (I): 1 wherein R1 is an alkyl group optionally substituted with a hydroxy, carboxy, carboxy ester, acyl or carbonato group; X is S, O or NnullR6; R6 is an optionally substituted alkyl group; R2, R3, R4 and R5 independently represent a hydrogen atom, a halogen atom or an alkyl, an alkoxy, a thio-alkoxy, a nitro, a cyano, a carboxy, a carboxy ester, an acyl, an aldehyde, an acylamido, a sulphonamido, an acylamino, a carbonato, a hydroxy or an aryl group or at least one of R2 and R3, R3 and R4 and R4 and R5 independently represent the atoms necessary to form a carbocyclic or heterocyclic group or at least one of R1 and R5 and R2 and R6 independently represent the atoms necessary to form a heterocyclic ring; and compounds represented by formula (II): 2 wherein R7 is an optionally substituted alkyl group; Y is S, O or NnullR10; R10 is an optionally substituted alkyl group; R8 and R9 independently represent a hydrogen atom, a halogen atom or an alkyl, an alkoxy, a thio-alkoxy, a nitro, a cyano, a carboxy, a carboxy ester, an acyl, an aldehyde, an acylamido, a sulphonamido, an acylamino, a carbonato, a hydroxy or an aryl group or R8 and R9 represent the atoms necessary to form a heterocyclic or a non-aromatic carbocyclic ring or at least one of R8 and R10 and R9 and R7 independently represent the atoms necessary to form a heterocyclic ring; and both R8 and R9 cannot both be an alkyl group.
