Beschreibung
Zusammenfassung:	A pressure-sensitive or heat-sensitive recording material in which the colour reactant system contains, as main components (A) a polycyclic compound of the formula (1) in which X is a monocyclic or polycyclic aromatic or heteroaromatic radical, Y is a substituent detachable as an anion, Q1 is-O-,-S-, or Q2 is -CH2-, -CO-, -CS- or-S02- and R is hydrogen, C1-C12alkyl, C5-C10cycloalkyl, aryl such as phenyl or aralkyl such as benzyl, and ring A is an aromatic or heterocyclic radical having 6 ring atoms, which can have an aromatic fused ring, it being possible for both ring A and the fused ring to be substituted, (B) an organic condensation component capable of forming a chromogenic compound with component (A) and (C) an electron-withdrawing and a colour-developing component.
