Beschreibung
Zusammenfassung:	Light-sensitive compounds are described which have the formula (I) wherein R1 and R2 denote H or alkyl, R3 and R4 denote H or 4,6-bis-trichloromethyl-s-triazin-2-yl, R5 and R6 denote H or halogen, alkyl, alkenyl or alkoxy, and Ar denotes a mononuclear to trinuclear aromatic group. These compounds are suitable as photoinitiators for free-radical polymerizations or as photolytic acid donors for acid-cleavable compounds, and for cross-linking and color formation reactions. They are distinguished by a high sensitivity in various spectral ranges.
