Self-adhesive dental material

A self-adhesive, radiation curable, polymerizable dental material comprising

• A) a monomer component comprising
• a) at least one at least difunctional urethane (meth)acrylate, wherein in each case independently urethane (meth)acrylate is selected from urethane methacrylate and urethane acrylate,
• b) at least one hydrophilic alkylene oxide-based di-functional (meth)acrylate-based crosslinker, which i) does not comprise urethane (meth)acrylate and/or ii) does not comprise aromatic residues, or a mixture of at least two of these crosslinkers, wherein in each case independently one (meth)acrylate is selected from methacrylate and acrylate,
• c) at least one olefinic acid ester of a phosphoric acid and/or at least one olefinic acid ester of a thiophosphoric acid,
• d) at least one initiator and/or initiator system each having an absorption maximum of 420 to 550 nm and comprising i) diketone and at least one ii) co-initiator selected from a tert-amine and a 1,2-methylenedioxybenzene;
• and
• g) disubstituted 4,4′-di(oxabenzene)dialkylmethane of the formula IX
• with R1, R2, R5 and R6 in Formula IX each independently selected from H or C1 to C4-alkyl, and with R3 and R4 each linear and divalent C1 to C4 alkylene with n=2 to 15 and m=2 to 15;
• and optional
• B) a filler component comprising at least one dental glass or mixtures of dental glasses, wherein the total composition of the dental material is 100% by weight wherein
• i) diketone and ii) co-initiator are present at a molar ratio of ii):i) of greater than or equal to 1.1, wherein i) the diketone is present at greater than or equal to 0.2% by weight in the total composition.
