Description

Technical Field

[0001] The utility model relates to the technical field of film pasting, in particular to a transparent bottom spray-painted film. Background Art

[0002] The existing transparent inkjet film includes a transparent inkjet layer and a base paper, and a self-adhesive layer is coated on the reverse side of the inkjet surface of the transparent inkjet layer, and then the base paper is pasted on the self-adhesive layer. When in use, it is only necessary to spray the image on the upper surface of the transparent inkjet layer, then peel off the base paper, and paste the transparent inkjet layer on a transparent plate such as glass or a car window. However, when this type of transparent inkjet film is in use, since its adhesive surface is a complete plane, it is not possible to quickly and efficiently exhaust air during the film pasting process, and bubbles are easily formed; moreover, since the image is located on a transparent carrier, the color of the picture cannot be displayed, so the contrast of the picture is very low. Utility Model Content

[0003] In order to make up for the deficiencies in the prior art, the utility model provides a transparent bottom spray-painted film, and the technical solution adopted is as follows:

[0004] A transparent bottom inkjet film comprises from top to bottom an ink absorbing layer, a substrate layer, a white color developing film layer, a reflective layer, an adhesive layer and a release film layer, wherein the white color developing film layer is evenly distributed with a plurality of light-transmitting holes, and a side of the adhesive layer in contact with the release film layer is densely covered with a plurality of protruding embossings.

[0005] Furthermore, the total area of ​​the plurality of light-transmitting holes accounts for 40-50% of the area of ​​the white color-developing film layer.

[0006] Furthermore, the aperture of the light-transmitting hole is 1-1.5 mm.

[0007] Furthermore, the thickness of the adhesive layer is 0.01-1.5 mm, the height of the embossing is 0.01-1.0 mm, and the distance between two adjacent embossings is 0.2-6.0 mm.

[0008] Furthermore, the shape of the embossing is circular, rectangular or regular polygonal.

[0009] Furthermore, the substrate layer is PVC, PET, or TPU.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The transparent bottom inkjet film of the utility model is provided with a white color developing film layer under the base material layer, which can clearly display the image sprayed on the ink absorbing layer, enhance the contrast of the image on the ink absorbing layer, and make the image display clearer; a reflective layer is provided on the white color developing film layer, and light can pass through the light-transmitting holes at night and be reflected by the reflective layer, so that the image can also be observed at night; the adhesive layer is provided with embossings, and exhaust channels can be formed between the embossings, so that exhaust can be timely exhausted when the film is applied to avoid the generation of bubbles.
