<p>Coating of substrates comprises applying a composition (C) on at least one side of a substrate, where (C) comprises e.g. an inorganic compound (IC) containing at least one metal and/or half metal; drying (C); applying at least one coating to the coated side of the substrate, where the coating contains e.g. a silane (I), oxide particles, and an initiator; drying the coating; applying at least one further coating to the coated side of the substrate, where this further coating comprises (I) and an antimicrobial and/or biocidal substance, and then drying. Coating of substrates comprises: (a) preparing a substrate, (b) applying a composition (C) on at least one side of the substrate, where (C) comprises: (1) an inorganic compound (IC) containing at least one metal and/or half metal selected from Sc, Y, Ti, Zr, Nb, V, Cr, Mo, W, Mn, Fe, Co, B, Al, In, TI, Si, Ge, Sn, Zn, Pb, Sb and/or Bi; and (2) at least one element selected from Te, Se, S, O, Sb, As, P, N, C and/or Ga; (c) drying (C); (d) applying at least one coating to the side of the substrate coated in step (b), where the coating contains: (i) silane of formula (Z 1>)Si(OR) 3 (I); (ii) oxide particles selected from oxides of Ti, Si, Zr, Al, Y, Sn, Zn and/or Ce; (iii) an initiator; and (iv) optionally zinc, zinc salt, zinc complex, silver, silver salt and/or komplexed silver; (e) drying the coating applied in step (d); (f) applying at least one further coating to the side of the substrate to which the coating in step (d) was applied, where this further coating comprises: (1) (I); (2) an antimicrobial and/or biocidal substance selected from substances containing Zn, Zn salts, Zn complexes such as zinc acetylacetonate, Zr, Ag, Ag salts, Ag complexes, Sn and/or Sn compounds; and (3) an initiator; and (g) drying the coating applied in step (f).
