Description of the invention: [Technical field to which the invention pertains] (9) The invention relates to a protective film, in particular to an optical film surface having an optical microstructure S-slit, for preventing an optical film A protective film structure that is produced during processing and transportation to traces and dirt. [Prior Art] According to recent years, due to the transportation or processing of optical parts and electronic materials, it is often used to prevent parts in the state of a given sheet-like package or in the state of being attached to an adhesive tape. The surface is smoothed or materialized, and the surface protective film is used in the field of = sub-electronic parts. It is especially used in the field of light, especially the light of the microstructure is required to protect the surface from the surface to prevent the 2 microstructures from being Processing, moving, or staining. The protective film i of the conventional one, as shown in FIG. 1, the protective film has an adhesive 1 and a non-adhesive layer i2 'the non-adhesive layer 2 is a thin layer of p, and the adhesive layer 1 1 is For the single layer coating on the non-adhesive layer 2 =: the high viscosity of the adhesive layer 11 can be attached to the light - ^ first sub-microstructure 'to achieve the purpose of protecting the optical. Only in production, 'usually will be rolled into a cylindrical shape to protect the transport, please refer to _ 2, the protective film 1 in the state of the retraction, the point I;: 1 will be 1 2 When the protective film 1 is to be attached to the surface of the film, the protective film 1 is pulled out to cover the surface of the optical layer, and the adhesion layer η of the protective film is The non-dot 1397765 layer 12 is overlapped and extruded by the layer. In addition, since the contact area between the layer U and the non-layer 12 is large, there is often a defect that is not easily peeled off, so that the film is formed. 1 When pulling out, the valley easily causes the non-adhesive layer 12 to be deformed and deformed, so that the use of the loading agent can be replaced by a release agent, for example, a p〇lyvinyl address is substituted for the adhesive layer 1; [the high viscosity turns, although it can be solved No (4) detachment from the non-adhesive layer 1 2, but due to the high cost of the _ release agent, and the possibility of nugratlon, once the release agent of the non-adhesive layer 2 migrates to On the surface, it will cause the lack of staining of the release agent.为了In order to reduce the contact area of the adhesive layer 1 and the non-adhesive layer of the protective film 1 , the other phase is issued, and the protective film 2 has an adhesive layer 21 and a non-adhesive layer 2 2, the non-adhesive layer 2 2 is a film of p E material, and the adhesive layer 2 丄 is a single layer set on the hybrid layer 2 2, the high secret turn, the bottom layer 2 1 The method is set on the non-adhesive crucible 2 2 to make the adhesive layer of the adhesive layer 21 form a point-like distribution, and by adhering the crucible 21! ^Adhesive glue can adhere to the optical microstructure of the rough surface of the optical film, and achieve the purpose of Baoxian film. Although the adhesive layer 2 of the protective film 2 reduces the contact area with the non-adhesive layer 22 by means of a ''-like cloth shape, the effect of easy peeling is obtained'. However, the hybrid layer 2 is still mixed. The adhesive is also highly adhesive to the bismuth (4). Therefore, when the protective film 2 is used, there is still a lack of residual glue. v As shown in the fourth step, the protective film 3 has an adhesive layer 31 and a non-sticky layer 32 filament-p_-_, wherein the surface layer of the 曰3 2- side is formed in a large number. The recessed portion 3 is not a single layer, and the recessed portion 3 2 1 which is resistant to == 3 2 can be used to apply the adhesive of the adhesive layer 3, and only the recessed portion 3 of the non-adhesive layer 3 2 Between, make the fresh Μ: only the shoulders in the formation of the point of the eight _ layer 3 1 division can also be sticky = contact: the protective film 3 in the winding 'the _31 and the non-曰 曰 2 contact area 'However, the adhesive layer 3 is still a highly adhesive adhesive which is doped with a tackifier. Therefore, when the protective film 3 is used, it is also impossible to overcome the defect of the residue. The applicant of the case is a professional manufacturer of protective film. There is a protective film of Zhongzhi, which has the defects of easy to produce residual glue and is not easy to be peeled off. The invention is finally obtained through continuous research and experiment.
