1. A coating structure for coating a reflector for use in a headlamp of a motor vehicle, the coating structure comprising:
a metallic base layer for application to a substrate;
a layer of fluorocarbon arranged on the metallic base layer; and
at least one high-refractive index dielectric layer (H) with a refractive index of ≥1.8 in the visible spectral range arranged on the layer of fluorocarbon,
where the material of the high-refractive index dielectric layer (H) does not feature any absorption lines in the visible spectral range.
