Field of the Invention The present invention relates to a method and a structure for producing a reflective meal, and more particularly to a method for manufacturing a double-sided reflective film and a structure thereof. [Prior Art] Generally, in order to increase the visibility of people or objects at night, reflective films are usually placed on objects such as helmets, safety vests, clothes, magazine strips, traffic facilities or transparent partitions to increase objects. Visibility at night or alert and safety. In addition, the reflective film can also be designed in the form of a pattern or typeface to increase variability and aesthetics. Please refer to Fig. 1 for a method of manufacturing a conventional reflective film, such as the Patent Law No. 1309202 of the Republic of China, "Printing Processing Method with Reflective Effect". The manufacturing method of the conventional reflective film comprises an adhesive layer setting step, a gold oil spray step, a reflective bead addition step and a coloring step. The adhesive layer is disposed by applying a thermal transfer adhesive layer 92 to a substrate 91, and then applying a silver paste layer 93 to the thermal transfer adhesive layer 92. The gold oil spraying step is performed by spraying gold oil on the silver paste layer 93. The retroreflective bead addition step is to place the retroreflective bead on the gold oil, position the retroreflective bead by gold oil, and then use a flattening action to form a reflective bead layer 94 together with the reflective bead. The coloring step is to print the pigment layer 95 on the reflective bead layer 94 to obtain a transfer film having a reflective effect. In addition, in order to prevent the reflective beads in the reflective bead layer 94 from falling off and increasing the adhesion between the reflective bead layer 94 and the pigment layer 95, a first gold oil layer 941 is further disposed on the surface of the reflective bead layer 94. The first gold oil layer 941 is interposed between the reflective bead layer 94 and the 201122535 pigment layer 95. Further, in order to reduce the chance of pigment detachment in the pigment layer 95, a second gold oil layer 951 is additionally provided as a surface protective layer of the pigment layer 95. The reflective film structure manufactured by the above-mentioned conventional method for producing a reflective film comprises a substrate 91, and the heat transfer adhesive layer 92, the silver paste layer 93, and the reflective bead layer 94 are sequentially stacked on one surface of the substrate 91. The first gold oil layer 941, the pigment layer 95 and the second gold oil layer 951 are combined to form a reflective film structure. The method for producing a conventional light-reflecting film of the above-mentioned Japanese Patent No. 1,309,202 can be used to spray the first gold oil layer 941 to prevent the reflective beads from falling off and to increase the light-reflecting effect. However, the reflective film can only be unidirectionally reflected. When the surface of one of the light-transmitting objects is attached, the other side is not provided with the reflective bead layer 94, so that light can only be reflected from one side of the substrate 91. When light is incident from the other side of the substrate 91, light cannot be reflected from the other side of the substrate 91, and the effect of double-sided reflection cannot be achieved. For the above reasons, the method of manufacturing the above-mentioned retroreflective film and its structure are indeed necessary for improvement.

The above and other objects, features, and advantages of the present invention will become more apparent from the aspects of the invention. 2 is a view showing a method for manufacturing a double-sided reflective film according to a preferred embodiment of the present invention, comprising the steps of: a first adhesion layer coating step 'S1, a first light-reflecting layer coating step S2, and a first mirror surface. The layer coating step S3, a spacer layer coating step S4, a second mirror layer coating step S5, a second light reflecting layer coating step S6, and a second adhesion layer coating step S7. Referring to Figures 2, 4 and 5, the first adhesion layer coating step S1 of the preferred embodiment of the present invention applies an adhesive coating on a substrate 11 to form a first adhesion layer 12. . The substrate 11 is selected from a transfer material or a transparent material. The material of the transfer material is preferably polyethylene terephthalate (PET), Ortho-Phenylphenol (OPP) or paper. The material of the transparent material may preferably be acrylic (PMMA), glass, polyethylene terephthalate (PET) or polycarbonate (PC). Preferably, the adhesive coating can be a bridging agent, a hot melt, a pressure sensitive adhesive or a disposable ink, such that the first adhesive layer 12 can serve as an adhesive layer for adhesion. In addition, in order to make the first adhesion layer 12 have a color or a protective layer effect, the adhesive coating may be mixed with other Lu paint according to user requirements, and other coating materials may be gold oil, ink, protective oil, pigment or The paint or the like provides the first adhesion layer 12 with color, adhesion and protection functions. Referring to FIGS. 2 and 6 to 8, the first light-reflecting layer coating step S2 applies a transparent gold oil to the first adhesion layer 12, and then a plurality of 'reflective beads 13a are interspersed with On the surface of the transparent gold oil, after flattening, the transparent gold oil and the plurality of reflective beads 13a together form a first light reflecting layer 13. In detail, as shown in FIG. 6, the transparent gold oil is first applied to the first adhesion layer 12, and the transparent gold oil is used as a medium to spread a plurality of reflective beads 13a on the surface of the transparent gold oil. In the transparent gold oil, in order to adhere the fixed reflective 201122535 bead 13a, the area of the transparent gold oil applied to the first adhesive layer 2 can be adjusted according to the reflective bead setting area. As shown in Fig. 6, a pressure roller is then uniformly applied to the reflective beads 13a to allow a plurality of retroreflective beads 13a to be further embedded in the transparent gold oil. The reflective bead setting area affects the reflective area, so that the first reflective layer 13 has a partial or total reflection effect, so that the reflective bead setting density can be changed according to requirements. As shown in Fig. 8, after flattening, the transparent gold oil and the plurality of reflective beads 13a together form a first reflective layer 13 having a smooth surface, and the reflective beads 13a are embedded in the first reflective layer. Referring to FIGS. 2 and 9, the first mirror layer coating step S3 forms a first mirror layer on the first light reflecting layer 13. Wherein, the first mirror layer 14 is a metal layer, and the metal layer is preferably formed by a mirror surface treatment method, for example, directly, or formed by coating, vacuum electricity, steaming, cooling, and blanching. The first light reflecting layer 13 is on. The first mirror layer 14 is used as a reflective layer. Preferably, the reflective bead 13a in the first light reflecting layer 13 is in contact with the first mirror layer 14, and the forward light is incident on the first through the first adhesive layer 12 and the first reflective layer 13 When the surface of the mirror layer 14 is reflected, the incident light can be retroreflected by the first mirror layer η reflection. Referring to Figures 2 and 10, the spacer layer coating step S4 applies a spacer coating as a spacer layer 15 to the first mirror layer 14. The spacer layer 15 is used to separate the layers completed above and the layers that are not subsequently performed. Among them, the spacer paint is preferably gold oil, and may also be a bridging agent, an ink, a protective oil, a hot sol, a pressure sensitive adhesive, and a disposable ink. Referring to the second mirror layer coating step S5 shown in FIGS. 2 and 11 , a second mirror layer 16 is formed on the spacer layer 15 such that the spacer layer 201122535 15 is interposed between the first mirror layer 14 and Between the second mirror layers 16. The second mirror layer 16 is combined with the first mirror layer 14 by the spacer layer 15 for allowing light incident from the forward or reverse direction to pass through the first mirror layer 14 and the second mirror surface, respectively. Layer 16 reflects so that light incident in the forward or reverse direction does not penetrate or interfere with each other. The second mirror layer 16 is also obtained by mirror processing. The detailed method is the same as the first mirror layer coating step S3 described above, and therefore, the details are not described herein again. Referring to FIGS. 2 and 12 to 14, the second reflective layer coating step S6 is performed by applying transparent gold oil to the second mirror layer 16, so that a plurality of reflective beads 17a are interspersed in the transparent gold. After the oil is pressed, the transparent gold oil and the plurality of reflective beads 17a together form a second light reflecting layer 17. In detail, as shown in FIG. 12, a transparent gold oil is first applied to the second mirror layer 16, and the transparent gold oil is used as a medium to spread a plurality of reflective beads 17a on the surface of the transparent gold oil. . As shown in Fig. 13, the pressure roller is uniformly applied to the reflective beads 17a so that the plurality of reflective beads 17a can be further embedded in the transparent gold oil. As shown in Fig. 14, after flattening, the transparent gold oil and the plurality of reflective beads 17a together form a second reflective layer 17 having a flat surface. Referring to Figures 2 and 15, a second adhesion layer coating step S7 of the preferred embodiment of the present invention applies an adhesive coating to the second light reflecting layer 17 to form a second adhesion layer 18. The detailed method is the same as the first adhesion layer coating step S1 described above, and therefore, it will not be repeated herein. The second adhesive layer 18 is for preventing the reflective beads 17a from falling off from the second light reflecting layer 17, thereby affecting the reflective effect. Furthermore, the second adhesive layer 18 can also contain a high transparency coloring material, so that the reflected light can be colored, and the reflective effect and variability of the double-sided reflective film of the present invention is increased. Thus far, the method of manufacturing the double-sided reflective film of the present invention has been completed. In addition, as shown in FIGS. 3 and 16, after the second adhesion layer coating step S7 is completed, a protective layer coating step S8 is preferably further performed. The protective layer coating step S8 applies a protective coating. A protective layer 9 is formed on the second adhesion layer 18. The protective coating may comprise a protective oil, a hot melt adhesive, a pressure sensitive adhesive or a gold oil. By providing the protective layer 19, the second adhesion layer 18 can be prevented from falling off or being damaged. Furthermore, the pressure can be applied to the protective layer 19 by applying pressure, for example, to increase the adhesion between the layers. The protective layer 19 can also be used as an adhesive layer, so that the double-sided reflective film can be used. The protective layer 19 is adhered to any object to be attached. In addition, a transfer film is preferably disposed on the protective layer 19 to maintain the structural integrity of the double-sided reflective film when the double-sided reflective film is attached to the object, thereby increasing the convenience of use of the double-sided reflective film. Preferably, the transfer film is a printable film or any other conventional transfer film. In addition, the method for manufacturing the double-sided reflective film according to another embodiment of the present invention is preferably further disposed on the first adhesion layer 12 after the first adhesion layer 12 is coated. A first transparent color printing layer 121 is disposed on the first adhesion layer 12 such that the first transparent color printing layer 121 is interposed between the first adhesion layer 12 and the first reflective layer 13. Moreover, after the coating of the second adhesion layer 18 is completed, a second transparent color printing layer 181 is disposed on the second adhesion layer 18, so that the second transparent color printing layer 181 is interposed therebetween. Between the second adhesion layer 18 and the protective layer 19. The user only needs to use any of various conventional printing methods such as screen printing, embossing, gravure printing, computer color inkjet, lithography or flexographic printing to complete the first and second transmissive color layers. , 181 preparation and setting. The patterns on the first and second transparent color printing layers 121, 181 can also be selected as different patterns according to requirements to increase the color and pattern variability of the double-sided reflective film. Referring to Fig. 15, the structure of the double-sided reflective film of the present invention is laminated by the above steps. The double-sided reflective film structure comprises the substrate 11 , and the first adhesion layer 12 , the first light-reflecting layer 13 , the first mirror layer 14 , and the first surface layer 14 are sequentially stacked on one surface of the substrate 11 . The spacer layer 15, the second mirror layer 16, the second light reflecting layer 17, and the second adhesion layer 18 together form the double-sided reflective film structure of the present invention. The first light reflecting layer 13 and the second light reflecting layer 17 are respectively dispersed with a plurality of reflective beads 13a and 17a. The first adhesive layer 12 and the second adhesive layer 18 are made of an adhesive coating for making the double-sided reflective film structure viscous. By disposing the first mirror layer 14 and the second mirror layer 16 on both sides of the spacer layer 15, the light incident by the second adhesion layer 18 or the first adhesion layer 12 is respectively borrowed. Reflected by the first mirror layer 14 or the second mirror layer 16, the function of double-sided reflection is achieved. So far, the double-sided reflective film structure of the present invention has been completed. In addition, as shown in FIG. 16, the protective layer 19 may be disposed on the second adhesive layer 18, and the protective layer 19 is made of a protective coating to prevent the second adhesive layer 18 from being damaged or Peel off. Referring to FIG. 17 again, in the structure of the double-sided reflective film of the present invention, the first transparent color printing layer 121 is preferably disposed on the first adhesive layer 12 by the above steps. The first transparent color printing layer 121 is interposed between the first adhesion layer 12 and the first light reflection layer 13 . In addition, the second transparent color printing layer 181 may be disposed between the second adhesion layer 18 and the protective layer 19. Thereby, the variability of the color and pattern of the double-sided reflective 201122535 of the present invention can be increased. The user can make different designs according to the requirements, and only need to use various conventional printing methods such as screen printing, embossing, gravure, The production of the first and second light-transmissive color printed layers 121, 18 can be completed by computer inkjet, lithography or flexographic printing. In use, the double-sided reflective film can be optionally placed in any place by transfer or direct printing. When the substrate of the double-sided reflective film is selected as a transfer paper, the surface of the second adhesive layer 18 or the protective layer 19 of the double-sided reflective film can be transferred by thermal transfer, low-temperature thermal transfer or water transfer. Attached to one side of the object to be adhered to the object to be pasted. Among them, the thermal transfer system heats the adhesive coating in the transfer paper so that the transfer paper and the layer structure are attached to the object to be pasted. The water transfer method is that the double-sided reflective film is placed on the surface of the water, and the layer structure of the reflective film is uniformly written on the surface of the object to be pasted by the action of water pressure, and the water transfer method can be based on the water transfer method. The curved surface of the attached object uniformly coats the reflective film, and is particularly advantageous for transferring the object to be pasted with a complicated irregular curved surface. In addition, the present invention can stack the first adhesion layer 12, the first-reflective layer 13, the first mirror layer 14, and the separation layer by the design pattern required for the substrate η-surface to sequentially follow. 15. The second mirror layer 16, the second light reflecting layer, and the second adhesion layer 18 are placed on the pattern in a partially disposed manner. By using the substrate u as a base layer, the layers which are stacked on the substrate in accordance with the desired pattern can be transferred or otherwise transferred, and the pattern can be completely transferred to any object. In other words, even if the double-sided reflective film of the present invention is a complicated pattern, the layers which are partially disposed in accordance with the pattern can be easily transferred only by the substrate. The left side of the object is placed on the object to increase the three-dimensional sense of the double-sided reflective film. The invention 201122535 makes a partial emphasis according to the required design pattern, so that the double-sided reflective film achieves a stereoscopic reflection effect. Furthermore, please refer to Fig. 18, which is a schematic view showing the use of the double-sided reflective film. Referring to Figures 19 and 20, a partial enlarged view of Fig. 18 is used to illustrate the travel path of incident light rays in different directions. As shown in FIGS. 18 and 19, it is disclosed that the object to be pasted is a transparent object 2, and when light is incident from the substrate 11 toward the transparent object 2, light will penetrate the substrate 11 and the first adhesion. The layer 12 to the first light reflecting layer 13 collects light by the first mirror layer 14 and the reflective beads 13a of the first light reflecting layer 13 to reflect light in the forward direction, thereby achieving the reflective effect of the first surface 21. In addition, as shown in FIGS. 18 and 20, when light is incident from the second surface 22 of the transparent object 2 toward the first surface 21 of the transparent object, the light sequentially penetrates the protective layer 19 and the second adhesive layer 18 to the The second light reflecting layer 17 collects light by the second mirror layer 16 and the reflective beads 17a of the second light reflecting layer 17 to reflect the light in the forward direction, thereby achieving the reflective effect of the second surface 22. Referring to FIG. 18 again, the second mirror layer 16 and the first mirror layer 14 are respectively disposed on both sides of the spacer layer 15 to make the light incident from the substrate 11 toward the transparent object 2 or The light incident on the second surface 22 of the transparent object 2 toward the first surface 21 can be reflected by the first mirror layer 14 and the second mirror layer 16, respectively, so that the light incident in the forward or reverse direction is not Penetrate or interfere with each other. Referring again to Fig. 8, the double-sided reflective film manufactured by the present invention allows light to be retroreflected regardless of whether it is incident on the first surface 21 or the second surface 22 of the transparent object 2. Therefore, whether the first surface 21 or the second surface 22 of the transparent object 2 is viewed, the bright color pattern can be seen, and the color pattern in the double-sided reflective film or the first and second light transmissions of the 201122535 The color printed layers 121, 181 清楚 clearly reflect the effect of achieving double-sided reflection through the reflection of light. The invention provides a method for manufacturing a double-sided reflective film and a structure thereof to form a double-sided reflective film to achieve double-sided reflective effect. The invention provides a double-sided reflective film structure, by attaching the double-sided reflective film of the invention to the light-transmitting object, so that the light can be positively retro-reflected on both sides of the light-transmitting object to achieve the lifting of the light-transmitting object.
