Abstract

Processes for treating a wide variety of substrates with transparent, storage-stable and water-compatible inorganic/organic sols suitable for the surface functionalization comprising said transparent and storage-stable coating agent containing a water-compatible sol and water in a weight ratio of 100:1 to 1:500; said water-compatible sol obtained by mixing the following components: wherein R represents the same or different hydrocarbon groups with from 1 to 22 carbon atoms, optionally substituted with functional groups, which are bonded to the silicon atom through a carbon atom, optionally interrupted by oxygen, sulfur, nitrogen or the group NR3, with R3 being hydrogen or C1 to C14 alkyl;
