Compositions containing phosphonate-functional particles

A composition (Z) comprising

• (a) 0.02-200 parts by weight of particles (P) which contain at least one structural element of the formula [1],
• ≡Si—L—P(O)(OR1)2 [1]
• (b) 100 parts by weight of a binder (B),
• (c) 0-100 parts by weight of a curing agent (H) which is reactive with the binder (B), and
• (d) 0-1000 parts by weight of a solvent or solvent mixture, where
• L is a divalent aliphatic or aromatic hydrocarbon radical having 1 to 12 carbon atoms, whose carbon chain is optionally interrupted by nonadjacent oxygen atoms, sulfur atoms or NR2 groups, and which is optionally substituted by carbinol, amino, halogen, epoxy, phosphonato, thiol, (meth)acrylato, ureido, or carbamato groups,
• R1 is hydrogen, a metal cation, an ammonium cation of the formula —N(R2)4+, a phosphonium cation of the formula —P(R2)4+, or an aliphatic or aromatic hydrocarbon radical having up to 12 carbon atoms, whose carbon chain may be interrupted by nonadjacent oxygen atoms, sulfur atoms or NR2 groups, and which is optionally substituted by carbinol, amino, halogen, epoxy, phosphonato, thiol, (meth)acrylato, carbamato, or ureido groups, and
• R2 is a hydrocarbon radical having 1-8 carbon atoms.
