1. A method for producing a layered body, comprising the method steps of
I) providing
IA) a first composition Z1 comprising
an organic solvent OL1;
at least one organic noble metal complex compound EKV1 dissolved or dispersed in the organic solvent OL1 at the concentration K1;
and
IB) a second composition Z2 comprising
an organic solvent OL2;
at least one organic noble metal complex compound EKV2 dissolved or dispersed in the organic solvent OL2 at the concentration K2;
II) coating at least a part of the surface of a substrate with the first composition Z1 and heating the coated substrate at a temperature T1 to obtain a first layer S1 containing a noble metal in metallic form and having a thickness D1;
III) coating at least a part of the first layer S1 containing a noble metal with the second composition Z2 and heating the coated substrate at a temperature T2 to obtain a second layer S2 containing a noble metal in metallic form and having a thickness D2, which second layer at least partially covers the first layer S1 containing a noble metal;
wherein the organic noble metal complex compounds EKV1 and EKV2, the organic solvents OL1 and OL2, the concentrations K1 and K2, the thicknesses D1 and D2 and the temperatures T1 and T2 are selected or adapted in such a manner that the first and the second layer S1 and S2 containing a noble metal differ from one another in at least one of the following properties:
(α) electrical conductivity;
(β) porosity;
(γ) density;
(δ) specific surface unit.
