Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0017] A tensile anti -reflective film, such as Figure 1 and Figure 2 As shown, it comprises light -transmitting layer 2 and base layer 4, the end face of light -transmitting layer 2 and base layer 4 is provided with a plurality of oppositely arranged taper grooves 211 and containing grooves 41 respectively, the surface of containing groove 41 is covered with metal layer 3, the surface between light -transmitting layer 2 and base layer 4 is coated with a layer of colored dye, taper groove 211 and containing groove 41 are surrounded by glass bead 7, taper groove 211 and containing groove 41 are left with liquid guiding gap containing colored dye flow, in addition, light -transmitting layer 2 comprises resin layer and a plurality of prism units 21 arranged on the resin layer, taper groove 211 is provided on the surface of prism unit 21, weatherable film 1 is fixedly arranged on the side of light -transmitting layer 2 away from base layer 4, pressure sensitive adhesive layer 5 and release layer 6 are sequentially fixedly arranged on the side of base layer 4 away from light -transmitting layer 2.

[0018] As shown in Figure 1 and Figure 2As shown, specifically, a layer of resin material is coated on the working surface, and after cooling, a resin layer is formed, and then a micro-prism slurry is coated on the surface of the resin layer, and after curing, a plurality of prism units 21 are formed on the resin layer, thereby forming the light-transmitting layer 2;

[0019] The PET substrate is placed on the surface of the special mold, and then a layer of resin material is poured and pressed by the equipment to form the base layer 4 with good tensile effect, and a plurality of groups of accommodating grooves 41 are formed on the surface of the base layer 4 close to the surface of the special mold, and then the special mold close to the accommodating grooves 41 is removed, the focusing layer is coated on the surface, and then vacuum evaporation is performed on the surface to form a metal layer 3 for reflecting light on the surface of the accommodating grooves 41, and after cooling, glass microbeads 7 are added into the accommodating grooves 41 by spreading;

[0020] The surface of the base layer 4 where the accommodating grooves 41 are formed is sprayed with colored dye, and then the light-transmitting layer 2 is immediately pressed and combined with the base layer 4, the light-transmitting layer 2 is fixedly bonded to the base layer 4 through the resin layer, and after cooling, the release layer 6 coated with the pressure-sensitive adhesive layer 5 and the protective film are combined, thereby completing the production and manufacturing of the embodiment;

[0021] In the production method, in order to make the color transition of the light reflected by the glass microbeads 7 more orderly, the surface of the special mold is in an arc shape, so that the groove bottom of the accommodating grooves 41 is in an arc surface structure, in order to ensure the positional stability of the glass microbeads 7, the glass microbeads 7 are attached to the surface of the metal layer 3 and the taper groove 211, and in order to realize stable attachment, the pressure of the pressing machine between the light-transmitting layer 2 and the base layer 4 needs to ensure that the surface of the taper groove 211 does not extrude the glass microbeads 7 towards the accommodating grooves 41;
