ABSTRACT:
Composition with at least one polymerizable binder and at least one polymerization initiator, which contains at least one acylgermanium compound according to general Formula (I),in which R0is a substituted or unsubstituted C1-18-alkyl radical or an acyl group; R1and R2are H, an acyl group or have one of the meanings given for R3; R3is a branched or linear C1-18-alkyl radical which can be unsubstituted or substituted one or more times by —O—, —NH—, —NR—, —S— or interrupted by other groups, trimethylsilyl, hal-(CH3)2Si—[OSi(CH3)2]r−, (CH3)3Si—[OSi(CH3)2]r—, —COOH, —COO—R10, —CO—NR11R12, —CO-vinyl, —CO-phenyl, phenyl-C1-4-alkyl, phenyl, naphthyl or biphenyl, C5-12cycloalkyl, a 5 or 6-membered O, S or N-containing heterocyclic ring, halogen, OH, an aromatic C6-30radical which can be substituted or unsubstituted and/or interrupted by O, S or —NR—, or a branched, cyclic or linear C1-20alkyl, -alkenyl, -alkoxy or -alkenoxy radical; m is 1, 2 or 3; n is 0 or 1 and p is 0 or 1; wherein in each case two of the radicals R0, R1, R2or R3can be connected to each other accompanied by the formulation of a 5 to 8 member ring; and the use of acylegermanium compounds of Formula (I), for example, as initiator for radical polymerization.
