    摘要: Compounds of the formula (I), wherein R1, R2 and R10 independently of one another are C1-C20alkyl, phenyl, C1-C12alkylphenyl or phenyl-C1-C6alkyl; R3 and R4 independently of one another are hydrogen, C1-C20alkyl, NR6R7 or SR8, provided that at least one of R3 or R4 is NR6R7 or SR8; R5 is hydrogen or C1-C20alkyl; R6 and R7 independently of one another are C1-C20alkyl, or R6 and R7 together with the N-atom to which they are attached form a 5 or 6 membered ring, which optionally is interrupted by O, S or NR9 and which optionally additionally is substituted by one or more C1-C4alkyl; R8 is phenyl, biphenylyl, naphthyl, anthryl or phenanthryl, all of which optionally are substituted by one or more C1-C4alkyl; and R9 is hydrogen, C1-C20alkyl, C2-C4hydroxyalkyl or phenyl; exhibit an unexpectedly good performance in photopolymerization reactions.
