- 19 - ABSTRACT THERMALLY-SENSITIVE RECORD MATERIAL A thermally-sensitive record material with improved thermal response for a given total coatweight of thermally-sensitive composition or image-forming components has the thermally-sensitive composition applied separately in two or more adjacent layers, each of which contains colour developing coreactant material, rather than in the conventional single layer. The adjacent thermally-sensitive layers are formulated such that together they generate a substantially single colour final print in response to heat energy input. The colour developing coreactant materials in the layers may be the same or different and are typically bisphenols. The colour former is typically a fluoran leucodye.
