(Meth) acrylate-substituted iminooxidiazine dione derivatives

Dental filling composite comprising:

• 1 to 45 weight % iminooxadiazine dione derivative with the formula (I)
• in which
• X, Y and Z represent a (meth)acrylic acid radical of the formula (II)
• in which
• R1 is hydrogen, an aliphatic hydrocarbon radical with 1 to 14 carbon atoms, which can be interrupted by oxygen atoms, or an aromatic hydrocarbon radical with 6 to 16 carbon atoms,
• R2 is hydrogen, an aliphatic hydrocarbon radical with 1 to 5 carbon atoms or an aromatic hydrocarbon radical with 6 carbon atoms, only one of the radicals R1 and R2 being able to have the meaning hydrogen;
• n is 1 or 2;
• where the (meth)acrylic acid radical of formula (II) is bound to the radical of formula (I) via R1 or R2 and the binding point remaining at R2 or R1 is saturated by hydrogen, and where X, Y and Z can be the same or different;
• the individual radicals R can be the same or different and selected from alicyclic or aromatic hydrocarbon radicals with 5 to 10 carbon atoms or aliphatic hydrocarbon radicals with 1 to 10 carbon atoms;
• 0.01 to 5 weight % initiator for the radical polymerization;
• 0 to 50 weight % further radically polymerizable monomer;
• and
• 30 to 85 weight % filler.
