摘要：
Polymerizable dental material which contains at least one radically-polymerizable monomer and at least one bisacylphosphine oxide of the Formula I, in which R1 is a linear or branched C2 to C14 alkyl residue, which can be interrupted by one or more O atoms, PG-Y—R2—X— or a substituted or unsubstituted, aromatic C6 to C14 radical; R2 is absent or a linear or branched C1 to C20 alkylene radical, which can be interrupted by one or more O atoms; R3 is H, a linear or branched C1 to C6 alkyl residue or PG-Y—R2—X—; R4 is a linear or branched C1-C6 alkyl or —O—C1-C6 alkyl residue; R5 is H or PG-Y—R2—X—; R6 is H or PG-Y—R213 X—; PG is a polymerizable group; X is absent, O or S; Y is absent, O, S, an ester, amide or urethane group; the bisacylphosphine oxide having at least one PG-Y—R2—X group and X and/or Y being absent if R2 is absent.
