Beschreibung
Zusammenfassung:	The present invention relates to a process for the preparation of a hybrid sol-gel coating composition and to the hybrid sol-gel coating composition obtainable by this process: a) providing a first sol obtainable by a process which comprising mixing at least one hydrolysable silicon alkoxide and at least one silicon-organic alkoxide having at least one non-hydrolysable substituent bonded to the silicon atom being the non-hydrolysable substituent other than a substituted or un-substituted (C1-C4)alkyl, one or more C1-C8 alcohols, an aqueous solution of one acid catalyst, and one organic precursor; b) providing a second sol obtainable by a process which comprises mixing at least one hydrolysable metal alkoxide, one or more C1-C8 alcohols, a complexion agent, and an aqueous solution of one acid catalyst; and c) mixing the first sol with the second sol. It also relates to a process for coating a substrate and to the coated substrate obtainable by this process.
