| titleOfInvention | Heat sensitive recording material |
| abstract | A heat sensitive recording material comprising a recording layer formed on a substrate and containing at least one colourless or light-coloured colour former and at least one colour developer, the material being characterised in that the recording material gives a blue image, and the colour developer being at least one compound represented by the formula (1) wherein R 1 is unsubstituted or substituted phenyl, naphthyl or C 1 -C 20 alkyl, X is a group of the formula (a), (b), or (c), A is unsubstituted or substituted phenylene, naphthylene or C 1 -C 12 alkylene, or is an unsubstituted or substituted heterocyclic group, B is a linking group of formula: —O—SO 2 —, —SO 2 —O—, —NH—SO 2 —, —SO 2 —NH—, —S—SO 2 —, —O—CO—, —O—CO—NH—, —NH—CO—, —NH—CO—O—, —S—CO—NH—, —S—CS—NH—, —CO—NH—SO 2 —, —O—CO—NH—SO 2 —, —NH═CH—, —CO—NH—CO—, —S—, —CO—, —O—, —SO 2 —NH—CO—, —O—CO—O— and —O—PO—(OR 2 ) 2 , and R 2 is unsubstituted or substituted or aryl benzyl or C 1 -C 20 alkyl, with the proviso, that, it B is not a linking group of formula —O—SO 2 —, R 2 is unsubstituted or substituted phenyl, napthtyl or C 1 -C 8 alkyl. |
