Optionally, the number of the composite layers 100 may be at least three, and the color layers 120 in the composite layers 100 are different from each other, so that the decorative film can have a wider adjustable range of colors and richer colors on the premise of controllable thickness.
Optionally, the colored layer 120 may be an NCVM layer, and the NCVM layer has non-conductivity, so when the decoration film is applied to a cover plate of a mobile phone, signals received or transmitted by the mobile phone or a bluetooth headset will not be accumulated by the NCVM layer due to conduction, and thus the RF (radio frequency) performance and ESD (electrostatic discharge) performance of the mobile phone will not be affected, that is, the wireless product can achieve better receiving effect due to the design of the NCVM layer, and has no noise and no influence on human body.
Meanwhile, the NCVM layer has metal texture, so that the decorative film can ensure a sufficient color adjustable range, can show a colored metal effect and enhance a colorful effect.
Meanwhile, the NCVM layer has light transmission or semi-light transmission, so that the visual performance of the decorative film can be enhanced, the design of the product is more rich and varied, and the appearance is more beautiful and colorful.
Alternatively, the colored layer 120 has a thickness too thin to make the color effect less obvious, and a thickness too thick to make the decoration film thinner, so the thickness of the colored layer 120 may be set to 0.05 μm to 0.15 μm, such as 0.07 μm, 0.1 μm, 0.12 μm, and the like, and preferably 1 μm, to achieve both the color effect and the thinning design.

The transparent decorative film is colorless and transparent, has the light transmittance of more than 95 percent and good bonding strength, is applied to decorative films, and can further enhance the visualization performance of the decorative films.
Alternatively, the thickness of the adhesive layer 130 is too thick to affect the thinning performance of the decoration film, and the thickness is too thin to affect the adhesion effect, so the thickness of the adhesive layer 130 may be selected to be 10 μm to 20 μm, such as 12 μm, 15 μm, 18 μm, and the like, and preferably 15 μm, to achieve both the thinning design and the connection stability.
Optionally, the composite layer 100 may also include a cured sizing layer 140. The composite layer 100, whether the adhesive layer 130, the substrate layer 110 or the colored layer 120, is made of a soft material, so that the curing and shaping layer 140 can be disposed between the substrate layer 110 and the colored layer 120 to improve the structural stability of the decorative film.
Optionally, the cured sizing layer 140 may be a UV glue layer. Choose for use the UV glue film, can realize on the one hand that substrate layer 110 and coloured layer 120's effective connection, on the other hand can make composite bed 100 realize arbitrary molding and keep composite bed 100's structural stability, details about the principle below:
the UV glue film is softer before the solidification, can be used to realize being connected between substrate layer 110 and the coloured layer 120 under this kind of state to form composite layer 100, the whole material of composite layer 100 is softer this moment, when attached on spare parts such as the cell-phone apron that possess certain curved surface molding, be convenient for and the shape of cell-phone apron formation adaptation.
And then carrying out curing treatment on the UV glue. Specifically, the UV glue on the formed composite layer 100 is subjected to a UV curing process, such as ultraviolet light irradiation energy and baking, to achieve UV curing, thereby forming a cured setting layer 140, and further achieving setting of the composite layer 100.
Alternatively, the thickness of the curing shaping layer 140 is too thin, the effect of stabilizing the structure is not good, and the thickness is too thick, so that the thickness of the curing shaping layer 140 may be set to be 5 μm to 15 μm, such as 7 μm, 10 μm, 12 μm, and the like, and preferably 10 μm, to achieve the reduction of the composite layer 100.
Optionally, the cured sizing layer 140 may have an embossed texture, for example, UV glue is usually formed by embossing, which may improve the connection stability and simplify the manufacturing process.
Optionally, the substrate layer 110 may be a PET layer, and the PET plastic has a highly symmetrical molecular structure and a certain crystal orientation capability, so that the film has high film forming property and formability, and is suitable for manufacturing the decorative film in the present application.
Alternatively, the thickness of the substrate layer 110 is too thin, which is not strong in bearing capacity, and too thick, which is not beneficial for thinning the composite layer 100, so the thickness of the substrate layer 110 may be set to be 23 μm to 50 μm, such as 23 μm, 38 μm, 45 μm, and the like, and preferably 23 μm, to achieve both bearing capacity and thinning design.
It should be noted here that, because the thickness of the substrate layer 110 is 23 to 50 μm, the thickness of the curing shaping layer 140 is 5 μm to 15 μm, the thickness of the adhesive layer 130 is 10 μm to 20 μm, and the thickness of the colored layer 120 is 0.05 μm to 0.15 μm, even if the decorative film is provided with the three-layer composite layer 100 in total, the thickness of the decorative film does not exceed 0.17mm, and the thickness difference from the decorative film in the related art is small, that is, by adopting the design mode of the decorative film of the present application, not only can the thickness be ensured not to increase, but also more color adjustable ranges can be provided, and further the appearance performance of the decorative film can be ensured.
Optionally, the decorative film may further include an ink layer 200, where the ink layer 200 is stacked on the plurality of composite layers 100 and located on a side of the colored layer 120 away from the substrate layer 110. The ink layer 200 serves as a substrate layer, has hydrophilicity and lipophobicity, can prevent fingerprints, stains and the like from remaining in the decorative film, and further improves the appearance performance of the decorative film.
