ABSTRACT:
A heat-sensitive recording material comprising a base and, on top of the said base, a heat-sensitive layer containing a cyclic diazo component and a coupling component, the cyclic diazo component being a benzotriazine compound of the formula ##STR1## wherein Q is --CH.sub.2 --, --CO-- or --SO.sub.2 --, R is hydrogen, hydroxyl, or aryl or alkenyl, each unsubstituted or substituted by halogen, hydroxyl, cyano, lower alkoxy, lower alkylthio, acyloxy, lower alkoxycarbonyl or lower alkylsulfonyl, or is acyl, acyloxy or acylamino, cycloalkyl, or is aryl or aralkyl such as phenyl, phenylalkyl or naphthyl each unsubstituted or substituted on the ring by cyano, halogen, nitro, trifluoromethyl, lower alkyl, lower alkylthio, lower alkoxy, lower alkylcarbonyl or lower alkoxycarbonyl, or is a heterocyclic radical, and the benzene ring A is unsubstituted or substituted by halogen, cyano, nitro, lower alkyl, lower alkoxy, lower alkylthio, lower alkylcarbonyl or lower alkoxycarbonyl.
