<p>The leather finish (3) has a surface (4) consisting of a non-thermoplastic elastomer layer, in which hollow microspheres (5) are embedded. The spheres each have an air-tight covering (6) with a wall thickness of less than 2 Microm. They contain gas, the pressure of which is above the atmospheric pressure. The surface possesses raised points (7) in the shape of sphere segments above areas located above at least a large proportion of the spheres.</p> |
