Detailed Description
Example (b): the present application provides a film with Anti-glare (AG), Anti-Reflection (AR) and Anti-fingerprint (AF), which includes, in conjunction with fig. 1 and 2: the film comprises a film base layer 1, an adhesive layer 2, a release film 3, an anti-glare layer 4, an anti-reflection layer 5 and an anti-fingerprint layer 6.
One side of the film base layer 1 is sequentially provided with an adhesive layer 2 and a release film 3 from inside to outside; the other side of the film base layer 1 is provided with an anti-glare layer 4, an anti-reflection layer 5 and an anti-fingerprint layer 6 from inside to outside in sequence. The anti-glare layer 4 is prepared on the film base layer 1 by combining cured resin and UV transfer printing; the antireflection layer 5 is formed by alternately laminating a first preset number of high-refractive-index film layers and a second preset number of low-refractive-index film layers on the antiglare layer 4 in sequence; the anti-fingerprint layer 6 is coated on the anti-reflection layer 4.
The Adhesive layer 2 may be optical Adhesive (OCA). In practical application, the release film can be removed, the adhesive layer 2 is attached to the glass or the composite board and other substrates through the attaching process, the explosion resistance of the glass can be enhanced, and the glass is environment-friendly, low in cost and high in production yield.
The positive reflection (specular reflection) is large, the penetration light is greatly reduced, and the dazzling optical fiber and the light of the mapping are reflected light generated by the positive reflection, so that the dazzling and the mapping can be prevented by controlling the positive reflection. For the anti-glare layer 4, usually, AG glass is subjected to etching treatment on the glass surface, so that the reflective surface (flat mirror surface) of the glass becomes a non-reflective matte surface (rough surface), and UV transfer printing is performed by using AG glass as a mold and dispensing (UV glue), pressing, curing and film-separating to obtain an AG film on the surface of the film base layer 1. The anti-glare layer 4 has excellent characteristics of anti-glare, high hardness, friction resistance and the like, and compared with an anti-glare layer prepared in an additive mode, the anti-glare layer 4 prepared in a UV transfer mode has lower roughness and smoother hand feeling under the same haze, and the anti-glare effect of the anti-glare layer 4 realized in the transfer mode is more stable.
Optionally, the haze of the anti-glare layer 4 is 0.3-15.
The principle of antireflection is that light is reflected at the boundary between substances having different refractive indices, and the interference of the reflected light produces an effect of increasing and decreasing the reflection.

Since the outer layer is made of a material having a high refractive index, most of light is reflected when the light is incident from the uppermost surface, and thus antireflection cannot be achieved, the innermost layer and the outermost layer of the antireflection layer 5 are low refractive index film layers. By alternately laminating the high-refractive-index film layers and the low-refractive-index film layers, light can be reflected from the low-refractive-index material to the high-refractive-index material at the contact interface, and multiple reflections realize surface antireflection extinction.
Optionally, the thickness of the first low refractive index film layer 51 is 85 to 100nm, the thickness of the first high refractive index film layer 52 is 100 to 120nm, the thickness of the second low refractive index film layer 53 is 35 to 50nm, the thickness of the second high refractive index film layer 54 is 8 to 16nm, and the thickness of the third low refractive index film layer 55 is 35 to 55 nm. The reflection of the antireflection layer is less than 0.7%. The film layers can be alternately laminated in sequence by means of coating or coating.
The anti-fingerprint coating film simulates the lotus leaf effect, and the AF material is a fluorine-containing coating, has extremely low surface tension, can improve the performances of hydrophobicity, oil drainage, pollution prevention and the like of a screen, and also has the characteristics of wear resistance, high light transmittance and the like. For the anti-fingerprint layer 6, the anti-fingerprint layer 6 prepared on the anti-reflection layer 5 in a coating mode enables the surface of a product not to generate fingerprints easily and has good wear resistance according to the strong hydrophobic, anti-fingerprint and anti-oil stain capabilities of Europe.
Optionally, the water drop angle of the anti-fingerprint layer 6 is greater than 110 °.
