A process for the production of a multi-layer composite, wherein a coating layer is applied from a pigmented coating composition onto the front face of an NIR-opaque foil exhibiting low NIR absorption, wherein the pigment content of the coating composition consists 50 to 100 wt.% of at least one black pigment with low NIR absorption and 0 to 50 wt.% of at least one further pigment, which is selected in such a way that the coating layer exhibits low NIR absorption and that the multi-layer composite has a color with a brightness L* of at most 10 units, wherein the sum of the wt.% equals 100 wt.%, and wherein the coating layer is cured. |
