Patent ID: 8062700

Claim:
A method for coating substrates, comprising the steps of: a) preparing a substrate, b) applying a composition onto at least one side of the substrate, the composition containing an inorganic compound, said inorganic compound containing at least one metal and/or semimetal selected from the group Sc, Y, Ti, Zr, Nb, V, Cr, Mo, W, Mn, Fe, Co, B, Al, In, Tl, Si, Ge, Sn, Zn, Pb, Sb, Bi or mixtures thereof and at least one element selected from the group Te, Se, S, O, Sb, As, P, N, C, Ga or mixtures thereof, c) drying the composition applied in step b), d) applying at least one coating onto the at least one side of the substrate onto which the composition was applied in step b), said coating containing a silane of the general formula (Z 1 )Si(OR) 3 , where Z 1 is R, OR or Gly (Gly=3-glycidyloxypropyl) and R is an alkyl radical having from 1 to 18 carbon atoms wherein each R may be identical or different, oxide particles selected from the oxides of Ti, Si, Zr, Al, Y, Sn, Zn, Ce or mixtures thereof, and an initiator, and e) drying the coating applied in step d), the composition of step b) and/or the coating of step d) containing at least one IR radiation reflecting pigment comprising a core and an electrical current conducting layer containing tin oxides and/or titanium oxides applied on the core.
