Thermographic recording material or image-receiving material for dry copying processes comprising at least one layer and a substantially non-photosensitive reducible silver salt, a reducing agent, and optionally a toning agent or toning mixture, wherein the reducing agent corresponds to the following general formula: ##STR1## wherein: EACH OF R.sup.1, R.sup.3 and R.sup.5 (equal or different) represents hydrogen, a straight-chain or branched alkyl group comprising 1 to 9 carbon atoms, or a cycloalkyl group, with the proviso that R.sup.1 and R.sup.5 do not represent hydrogen simultaneously, R.sup.2 represents a straight-chain or branched alkyl group comprising 1 to 4 carbon atoms, or a cycloalkyl group, R.sup.4 represents hydrogen, or a straight-chain or branched alkyl group comprising 1 to 4 carbon atoms, or a cycloalkyl group, And wherein each of R.sup.1 and R.sup.2 together, R.sup.2 and R.sup.3 together or R.sup.4 and R.sup.5 together optionally represent a straight-chain or branched alkylene group for completing a 6-membered ring; provided that that R.sup.1, R.sup.5 or R.sup.3 does not represent t-butyl if the respective adjacent substituent(s) represent(s) a straight-chain or branched alkyl group.
