Abstract

The invention relates to a process for the marking of an object surface, wherein there is arranged in contact with, or a distance away from the object surface a carrier element, featuring on its side facing the object surface at least one metal coating embedded in other layers, whereby the layers in particular form a Low-E coating system and whereby a laser beam is directed onto the coating system and by reason of the laser irradiation material is transferred from the coating system onto the object surface to be marked, adhering thereto as a matrix with metallic nano-particles, whereby the matrix is formed of the substances originally present in the layers of the coating system. The invention furthermore relates to an object with an object surface marked according to this process.
