Abstract
Dental compositions and biphenyl di(meth)acrylate monomers are described. The dental compositions comprise at least one biphenyl di(meth)acrylate monomer comprising two aromatic rings connected with a C—C bond wherein the rings each comprise a substituent comprising a urethane moiety and a (meth)acrylate end group.
