Abstract

The adhesion of resin material to the solid substance of the tooth and to metals and metal alloys, for example, dental alloys, can be improved with a photo-polymerizable formulation containing hydroxyalkyl(meth)acrylates, urethanedi(meth)acrylates and, if applicable, esters of aromatic polycarboxylic acids possessing methacryloyloxy groups.
