Polymerizable dental material which contains at least one radically-polymerizable monomer and at least one bisacylphosphine oxide of the Formula I, n nin which R 1 is a linear or branched C 2 to C 14 alkyl residue, which can be interrupted by one or more O atoms, PG-Y—R 2 —X— or a substituted or unsubstituted, aromatic C 6 to C 14 radical; R 2 is absent or a linear or branched C 1 to C 20 alkylene radical, which can be interrupted by one or more O atoms; R 3 is H, a linear or branched C 1 to C 6 alkyl residue or PG-Y—R 2 —X—; R 4 is a linear or branched C 1 -C 6 alkyl or —O—C 1 -C 6 alkyl residue; R 5 is H or PG-Y—R 2 —X—; R 6 is H or PG-Y—R 2 13 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—R 2 —X group and X and/or Y being absent if R 2 is absent. |
