Abstract:
A substantially light-insensitive monosheet thermographic recording material comprising a support and on one side of said support a thermosensitive element, wherein said thermographic recording material contains at least one compound represented by formula (I): wherein M is hydrogen, an alkali atom or an ammonium group; R1 is an alkyl, alkenyl-, alkynyl-, thioalkyl-, thioalkenyl- or thioalkynyl-group in which the alkyl-, alkenyl- or alkynyl-group has 6 to 25 carbon atoms; X is —O—, —S— or —N(R2)—; and R2 is hydrogen, a —(CH2)mSO3M group or a group; and m is an integer between 1 and 5.
