摘要:
An aqueous dispersion with a pH of from 2 to 7, comprising (A) at least one swellable polymer or oligomer containing anionic and/or potentially anionic functional groups, (B) surface-modified, cationically stabilized, inorganic nanoparticles of at least one kind, (C) at least one compound selected from the group consisting of amphiphiles and organic compounds which are capable of forming chelate ligands, and (D) at least one crosslinking agent; method for its production and its use for producing highly scratch-resistant coatings, moldings, and self-supporting films.
