Abstract:
    The present invention relates to compounds of formula(I)in which R1 and R2 independently of one another are, for example, a group of formula(II); R3, R4, R5, R6 and R7 independently of one another are, for example, hydrogen, C1-C12alkyl, OR8, SR9, NR10R11, halogen or phenyl; R8, R9, R10, R11 independently of one another are, for example, hydrogen or C1-C12alkyl; R12 is, for example, C1-C8alkyl; R13 is, for example, C1-C12alkyl; R14 is, for example, hydrogen; Y is C1-C12alkylene, C4-C8alkenylene, C4-C8alkynylene or cyclohexylene, or is phenylene or C4-C40alkylene interrupted one or more times by -O-, -S- or -NR15-, or Y is a group of the formula (III), (IV), (V), (VI), (VII), (VIII), (IX), (X) or (XI); Y1 is as defined for Y with the exception of formula (V); R15 is hydrogen, C1-C12alkyl or phenyl; and R16 is hydrogen, CH2OH or C1-C4alkyl; and mixtures of these compounds with further photoinitiators are suitable for photopolymerizing compounds having ethylenically unsaturated double bonds.
