The metal primer layer 102 has a bonding surface for bonding to the surface of the base material 101 and a functional surface disposed opposite to the bonding surface; the first transition layer 103 is positioned on the functional surface, and the second transition layer 104 is positioned on the surface of the first transition layer 103 far away from the metal base layer 102; the color layer 105 is located on the surface of the second transition layer 104 far from the first transition layer 103. The second transition layer 104 is a titanium chromium transition layer.
The wear-resistant scratch-resistant film 10 in this embodiment has a good bonding force between the film layers through the structural design of the metal base layer 102, the first transition layer 103, the second transition layer 104 and the color layer 105, and the film has good wear-resistant scratch-resistant performance, and meanwhile, the wear-resistant scratch-resistant film 10 can display various colors.

The metal Ti priming layer, the metal Cr priming layer or the metal TiCr priming layer can provide stable support for the overall structure of the film, and the stability of the film is improved.
In one particular example, the first transition layer 103 is a TiCrN transition layer, a CrN transition layer, or a TiN transition layer. The second transition layer 104 is a TiCrCN transition layer or a TiCrN transition layer. The color layer 105 is a TiCrCN color layer, a TiCrN color layer, or a TiN color layer. Under the condition, the second transition layer 104 can better ensure the stress matching and the element matching between the first transition layer 103 and the color layer 105, better improve the bonding force among the first transition layer 103, the second transition layer 104 and the color layer 105, and better improve the wear-resisting and scratch-resisting performance of the film. The color layer 105 is a TiCrCN color layer, a TiCrN color layer, or a TiN color layer, and can make the film display various colors. When the color layer 105 is a TiCrCN color layer, a TiCrN color layer, or a TiN color layer, the film can exhibit a uniform gold color, and a gold-like film can be obtained. Golden series films are popular with customers and markets because of their noble, bright color appearance, but the cost of gold is high. When the color layer 105 is a TiCrCN color layer, a TiCrN color layer or a TiN color layer, the film can show uniform gold color, a gold-like film can be obtained, and the processing cost of the gold film can be effectively reduced.
