Abstract (en)
[origin: EP0320453A2] Thermally sensitive recording material with a carrier and positioned thereon a thermally sensitive layer containing a cyclic diazo component and a coupling component, where the cyclic diazo component is a benzotriazinecompound of the formula <IMAGE> where Q signifies -CH2-, -CO- or -SO2- and R signifies hydrogen, hydroxyl, unsubstituted or halogen-, hydroxy-, cyano-, lower alkoxy-, lower alkylthio-, acyloxy-, lower alkoxycarbonyl- or lower alkylsulphonyl-substituted alkyl or alkenyl, acyl, acyloxy or acylamino, cycloalkyl, aryl or aralkyl such as unsubstituted or cyano-, halogen-, nitro-, trifluoromethyl-, lower alkyl-, lower alkylthio-, lower alkoxy-, lower alkylcarbonyl- or lower alkoxy carbonyl-ring-substituted phenyl, phenylalkyl or naphthyl, or a heterocyclic residue and the benzene ring A is unsubstituted or substituted by halogen, cyano, nitro, lower alkyl, lower alkoxy, lower alkylthio, lower alkylcarbonyl or lower alkoxycarbonyl.
