Abstract:
1. A method for coating substrates, comprising: a) applying a composition to a first side of a substrate, the composition comprising an inorganic compound and the inorganic compound comprising at least one metal and/or semimetal selected from the group consisting of Sc, Y, Ti, Zr, Nb, V, Cr, Mo, W, Mn, Fe, Co, B, Al, In, Ti, Si, Ge, Sn, Zn, Pb, Sb, Bi and mixtures thereof, and at least one element selected from the group consisting of Te, Se, S, O, Sb, As, P, N, C, Ga and mixtures thereof, b) drying of the composition, c) applying at least one coating to the first side of the substrate to which the composition has been applied, the coating comprising a silane of the general formula (Z d) drying the coating, e) applying at least one barrier layer to a second side of the substrate, wherein the barrier layer has substantially no pores after drying and the barrier layer prevents substances from penetrating into the substrate, and f) drying the barrier layer to form a dry barrier layer, wherein the barrier layer comprises at least one film-forming polymer selected from the group consisting of a synthetic resin dispersion, a synthetic resin emulsion, polymaleic anhydride, vinyl methyl ether/maleic anhydride copolymer, vinyl butyl ether/styrene copolymer, melamine/formaldehyde condensate, urea/melamine condensate and mixtures thereof.
