Abstract

The present invention relates to a fluid phase method for producing indium oxide-containing layers, in which a composition comprising at least one indium oxo-alkoxide of the generic formula MxOy(OR)z[O(R′O)eH]aXbYc[R″OH]d with x=3-25, y=1-10, z=3-50, a=0-25, b=0-20, c=1-20, d=0-25, e=0, 1, M=In, R, R′, R″=organic remainder, X═F, Cl, Br, I, and Y═—NO3, —NO2, where b+c is =1-20 and at least one solvent is applied to a substrate, optionally dried, and converted into an indium oxide-containing layer, to the indium oxo-alkoxides of the indicated generic formula, to coating compositions comprising said indium oxo-alkoxides, to layers that can be produced by means of the method according to the invention, and to the use of said layers.
