Patent ID: 6949616

Claim:
Silane-resin composition, obtained by (i) at least partially hydrolytic condensation of at least the following components: (1) One or more sulfonic acid group-containing silane(s) with at least one group that can be cleaved under hydrolytic conditions, selected from silanes of formula (I): P a R 1 b SiX 4-a-b (I) in which P has the meaning of HOSO 2 —R, whereby R is an aliphatic or aromatic organic radical or contains such a one, and P is bonded via the latter to the silicon atom; R 1 represents a group that is bonded to the silicon atom via a carbon atom; X is a group which is sensitive to hydrolysis; a is 1 or 2; b is 0, 1 or 2; and a+b together are 1, 2 or 3, (2) one or more styryl functionalized silane(s), selected from those of general formula (II) (St) a R 1 b SiX 4-a-b (II) in which (St) is an optionally substituted styryl radical; radicals R 1 and X are defined as in formula (I); a means 1, 2 or 3; b means 0, 1, 2 or 3; and a+b together are 1, 2, 3 or 4, and (3) One or more silane(s) that carry a nitrogen-containing heterocyclic group, an amine group, or a sulfonamide group and having attached thereto at least one group that can be cleaved under hydrolytic conditions, selected from those of general formula (III) (Q) a R 1 b SiX 4-a-b (III) in which radicals R 1 and X and indices a and b are defined as in formula (I); (Q) is Het-R— or NH 2 SO 2 —R— or NHR 2 —R—, whereby R is defined above as in formula (I), R 2 means hydrogen, and Het is a heterocyclic group containing a nitrogen atom bound within the ring, (ii) wherein either the components are mixed before hydrolytic condensation, or mixing is performed during or after hydrolytic condensation of the components.
