摘要：
The invention relates to a composition with at least one polymerizable binder, wherein the composition contains a photoinitiator mixture which contains (a) at least one diacylgermanium compound of general formula (I)in which R1, R2 independently of each other are a linear C1-4-alkyl, or C2-4-alkenyl radical, which can be substituted by one or more polymerizable groups； R3, R4 independently of each other are in each case H, halogen, a branched or linear C1-4-alkyl or —O—C1-4-alkyl radical； R5, R6, R7 independently of each other are in each case H, halogen, a linear C1-20-alkyl, -alkenyl, -alkoxy or -alkenoxy radical, which can be interrupted by one or more —O—, —S— or —NR8— radicals and substituted by one or more polymerizable groups； and R8 independently is in each case H, a C1-20-alkyl, -alkenyl, -alkoxy or -alkenoxy radical, (b) at least one α-diketone and (c) at least one accelerator, as well as the use of the composition for example for producing a filling composite.
