[0003] However, traditional decorative translucent films such as INS and IML films can achieve pattern hiding or dot matrix texture, and the dot matrix dots can be seen after light is transmitted; the color and resolution accuracy are low, and the general texture can only achieve 2~3 bit color levels. There are texture color blocks in the gradient effect, and smooth gradient transition cannot be achieved.
[0004] Therefore, it is necessary to design a film with a light-transmitting gradient decorative effect to achieve a smooth transition of the texture gradient and avoid the appearance of texture color blocks or dot matrix. Summary of the invention

[0009] The first light transmittance is 0-10%, and the second light transmittance is 50-80%.
[0010] The diameter of the ink dots printed on the gradient layer is 0.01 mm-0.1 mm.
[0011] The direction of change from the first light transmittance to the second light transmittance includes the lateral direction, the longitudinal direction, the radial direction, and the direction along the pattern.
[0012] It also includes a decorative layer. The decorative layer and the gradient layer are located on both sides or on the same side of the substrate, and the gradient layer is close to the light source, and the decorative layer is close to the visual position.
