Abstract

Als thermische Entwicklungs- und Diffusionsförderungs­ mittel für das Wärmeentwicklungsverfahren eignen sich Verbindungen der Formel I. Mit den genannten Verbindun­ gen können höhere Farbübertragsdichten erzielt und/oder die Entwicklungszeit abgekürzt werden. worin bedeuten
X -SO₂- oder -CO-;
R¹ - R⁴ Alkyl, Cycloalkyl, Aralkyl oder Aryl;
R⁵, R⁶ Acyl oder einen Rest wie angegeben für R¹ - R⁴;
wobei R¹ zusammen mit R⁵, R² zusammen mit R⁶, R³ zu­ sammen mit R⁴ und/oder R¹ zusammen mit R² jeweils einen mindestens ein Stickstoffatom enthaltenden heterocyc­ lischen Ring bilden können.
