A polymerizable composition containing by weight (a) an (optionally radically polymerizable) silane or aluminum, zirconium or titanium compound (1-80%), (b) a radical polymerization initiator (0.1-5%) and (c) further radically polymerizable monomer(s) (0-60%) also contains (d) a radically polymerizable monomer (1-50%) with a phosphonic or sulfonic acid group and is such that the polycondensate of (a) and/or the monomer (c) is fluorine substituted. A polymerizable composition containing by weight a radically polymerizable silane of formula (I), a silane of formula (II) and/or aluminum, zirconium or titanium compound of formula (III) or (IV) (1- 80%); a radical polymerization initiator (0.1-5%); and further radically polymerizable monomer(s) (0-60%) also contains (d) a radically polymerizable monomer (1-50%) with a phosphonic or sulfonic acid group and of formula (V) and is such that the polycondensate obtained from (a) and/or the monomer (c) is fluorine-substituted.
