Abstract (en)
A thermographic recording material comprising a support and a thermosensitive element, the thermosensitive element containing a mixture of substantially light-insensitive silver salts of organic carboxylic acids with one or more carboxylic acid groups, an organic reducing agent for the mixture of substantially light-insensitive organic silver salts in thermal working relationship therewith and a binder, characterized in that the mixture of substantially light-insensitive organic silver salts contains a silver salt of a monocarboxylic acid and a compound exclusive of silver succinate represented by formula (I): AgOOC-R<1>-COOAg wherein R<1> is a straight chain hydrocarbon group with two or three carbon atoms substituted with one or more of =O, =S, =CR<2>R<3>, an alkyl group, an aryl group, an amino group, a substituted amino group, a cycloalkyl group, a hydroxy group, a thiol group, a sulphone group, an alkoxy group, an acyloxy group, a thioalkyl group, a thioaryl, a carbamic ester group, a halogen atom or a -(C=O)R<4> group; two of the substituents of R<1> selected from the group consisting of alkyl, thioalkyl, substituted amino and alkoxy groups may jointly comprise the atoms necessary to complete a carbocyclic or heterocyclic ring; R<2> and R<3> are independently hydrogen or an alkyl, substituted alkyl, hydroxy or thiol; R<4> is a hydroxy, alkoxy, alkyl or -NHR<6> group; R<6> is hydrogen or an alkyl group; a thermographic recording process therewith and a photothermographic recording process therewith.
