The invention relates to a dental material, which contains: at least one monomer, containing at least one radically polymerizable ehtylenically unsaturated group and at least one acid group; at least one monomer, which contains no acid groups and at least one radically polymerizable ethylenically unsaturated group; at least one photoinitiator; and at least one tertiary aromatic amine as a coinitiator, which amine has a benzene ring, to which at least one dialkylamine group and at least one further group are directly bonded. According to the invention, the further group is selected from carboxylic acid ester groups containing at least one polyoxyalkylene group having at least 2 oxyethylene and/or oxypropylene units; and amide groups.
