ABSTRACT:
Dye compounds of the formula ##STR1## wherein X is for example CH, C--CH.sub.3 or .sup.+ NOR L.sup.- ; R is inter alia C.sub.1 -C.sub.6 alkyl; R.sub.1 is for example C.sub.1 -C.sub.8 alkoxy or C.sub.1 -C.sub.12 alkyl; s is 0 to 4; R.sub.2 is for example hydrogen; Ar is for example a group ##STR2## Y inter alia is C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkoxy; r in the formula (A) is 0 to 5, in the formulae (B) and (E) is 0 to 9 and in the formula (D) is 0 to 7; and L is an anion;
in combination with an electron donor compound, especially a borate compound, are suitable as photoinitiators for the photopolymerization of radically polymerizable compositions.
