Zusammenfassung:Thermographic reproduction material which is stable to the later action of heat consists of or contains a heat-sensitive element that is removed, destroyed or converted into a less reactive cpd. by the imagewise application of heat (in form of infra-rec radiation or visible light); material is ten contacted with a reception sheet that contains a substance that reacts with the remaining heat-sensitive cpd. the remaining heat-sensitive parts being transferred together with a binder that may be present to the reception sheet. Heat-sensitive cpd. is e.g. 1-phenyl-3-pyradolidinone.
