Any of a mixture of ethylene-butadiene copolymers (PC + ABS). The substrate 11 can also be a glass, ceramic or metal substrate. [0016] The primer layer 13 may be formed by spraying an acrylic paint on the surface of the substrate 11. The primer layer 13 is a colorless, transparent or tinted paint layer having a smooth, flat surface which enhances the adhesion of the subsequent coating to the primer layer 13. The thickness of the primer layer 13 may be 30/zm. [0017] The first metal texture layer 15 may be formed on the surface of the primer layer 13 by vacuum plating. The vacuum coating may be vacuum sputtering, vacuum evaporation, or the like. The first metal texture layer 15 is a composite layer formed by laminating a plurality of layers of ruthenium pentoxide and a plurality of ruthenium oxide layers. The total number of layers of the pentoxide layer and the ruthenium dioxide layer may be between 3 and 7 layers. The first metal texture layer 15 may have a thickness of 50 to 500 nm. [0018] The second metal texture layer 17 is formed on a portion of the surface of the first metal texture layer 15 , and the second metal texture layer 17 is disposed on the first metal texture layer 15 to form a decorative pattern and an electronic device. Trademark or other textual graphics. The second metal texture layer 17 is a composite layer formed by laminating a plurality of layers of ruthenium pentoxide layer and a plurality of ruthenium oxide layers, and the outer metal layer of the second metal texture layer 17 combined with the first metal texture layer 15 is The material of the outer surface layer of the first metal texture layer 15 combined with the material is different, for example, when the outer surface layer of the first metal texture layer 15 is a tantalum pentoxide layer, the second metal texture layer 1 combined therewith The outer layer of 7 is a ceria layer and vice versa. The total number of layers of the ruthenium pentoxide layer and the ruthenium dioxide layer of the second metal texture layer 17 may be between 3-7 layers. The second metal texture 099112431 Form number A0101 Page 5 of 11 0992022032-0 201138595 The thickness of layer 17 can be 5〇_5〇〇nm. [0025] [0025] [0023] [0023] [0027] [0027] 099112431 The electronic device bribe 1G in the formation of (four) two metal "layers of the layer, the said - The metal f-sensing layer 15 and the second metal-feeling layer 17 respectively form two sets of reflected light of different colors for the incident light, and the two sets of reflected light can also form a strong color difference contrast, so that the human eye observes the color, Moreover, the color can also change the appearance of the pattern according to the angle of observation (10), giving a fashionable and beautiful enjoyment, which greatly improves the appearance appeal and competitiveness of the product. The topcoat layer 19 is a transparent protective lacquer layer having a thickness of from 1 G to 50/zm. ^ to form a topcoat layer 19_ lacquer (4) outer vat paint, which has a higher hardness, thereby providing better surface protection.
