Abstract

The invention relates to a composition which is self-adhesive to the hard tooth tissue, comprising: (A) 5 to 75 percent by weight of one or more mono or higher functional ethylenically unsaturated compounds which additionally have an acid functional group, wherein one of said compounds has a P—OH group, for instance a phosphoric, phosphonic or phosphinic acid group; (B) 2 to 50 percent by weight of one or more mono or higher functional ethylenically unsaturated compounds without any acid functional group; (C) 22.8 to 85 percent by weight of filling material(s), comprising at least one filling material that may react with component (A) in the sense of causing a ion exchange, neutralization, salt formation and/or chelate formation reaction; (D) 0.1 to 8 percent by weight of one or more initiators and optionally activators; (E) 0.1 to 20 percent by weight of further additives, for example, modifiers, wherein the weight ration in % of component (A) relative to component (B) ranges from 21 to 90: 10 to 79.
