Zusammenfassung:The print material a layer structure (7) with two layers (7a,7b). The two layers incorporate particles whose average size is less 2mu m. The particles are pigments on base of cobalt aluminates or iron cobalt. The particles are blue or black in color. A substrate (4) is provided with a triangular wave form like structure (5) having surface roughness in the range of 20-40mu m. The substrate is made of chromed, galvanic casted nickel metal sheet. The thickness of the layers is 0.5-8mu m. The layers are provided with sol gel material.
