Description of the Invention: [Technical Field] The present invention relates to an anti-wear optical film, and more particularly to an anti-wear optical film used in a liquid crystal display. [Prior Art] Compared to conventional cathode ray tube (CRT) displays, liquid crystal displays (Liquid Cristal Displays, LCDs) have become the mainstream display devices on the market due to their thinness, light weight, and low power consumption. Widely used in a variety of electronic products, such as televisions, notebook computers, personal computers, portable personal communication devices. ® The main structure of a typical LCD monitor consists of a liquid crystal panel and a backlight module. Since the liquid crystal panel itself does not have the ability to provide an active light source, it must be combined with a backlight module as a source of brightness. Therefore, the quality of the light source provided by the backlight module plays an important role in the development of the liquid crystal display. In order to increase the brightness of the overall LCD panel, some operators have chosen to increase the number of lamps. Although the increase of the lamp can increase the brightness, it will increase the volume of the entire backlight module, and the power consumption is too large, and it is not suitable for portable electronic products such as a notebook computer or a personal communication device. In addition, when too many lamps are in operation, a large amount of thermal energy is accumulated, which may affect the life of the lamps and other electronic components. In another method, a plurality of optical films are added to the backlight module, so that the light source can be uniformly and directionally transmitted to the surface of the liquid crystal panel, and the light source provided by the lamp tube can be effectively utilized. Since the addition of the optical film does not require a significant change in the other designs of the original backlight module, and no additional power is required, it has become a method widely used in the industry to increase the brightness of the panel. The optical film in the backlight module mainly utilizes a surface coated with a transparent ultraviolet curing resin and solidified to form a prism array structure to achieve the orientation of the light source. Since such a cured resin has a low surface hardness, it may wear or break the structure of the prism when assembling or handling the liquid crystal display. When the light is emitted from the lamp, the image or shape displayed on the liquid crystal display will be uneven, which will affect the quality of the image display. 201209109 In order to ensure the integrity of the prism structure formed by the surface curing resin of the optical film, the current production process of the optical film is carried out by attaching a protective film to the surface of the cured resin layer, such as the Republic of China Patent No. 95127482 and the 90113387. In the technology shown in the application, the upper and lower surfaces of the optical film are attached to the upper and lower surfaces of the optical film by using the upper and lower pressing techniques and the tension control to protect the surface microstructure on the optical film, thereby avoiding the liquid crystal display during shipment and transportation. The damage caused. Since the acquisition of protective film relies on foreign imports, the cost of purchasing materials is high, which accounts for 30% of the total raw material cost of optical film, which undoubtedly increases the manufacturing cost of the overall liquid crystal display. In addition, a filming process has to be added during the manufacturing process, which also complicates the overall process. SUMMARY OF THE INVENTION The main object of the present invention is to solve the problem of insufficient surface hardness of a conventional optical film and an additional mold clamping process. In order to achieve the above object, the present invention provides an anti-wear optical film comprising a substrate, and a film body comprising a photosensitive hardening resin disposed on the substrate, the film body comprising a reaction filler, the reaction filler The reaction filler has a decane compound of the formula (1) in a weight percentage of from 1 to 30 with respect to the film body:

The various optical films obtained were subjected to abrasion resistance test (test according to ASTM D1044-56) using a load weight: 5 〇〇g, test grinding revolutions: 1 ;; in the wear index 'The lower the index, the better the wear resistance), the adhesion Test (according to ASTM D3359-87 method to do a hundred grid test, 5B is the best, followed by 4B, guilt, 2B and m), wrong pen hardness test (according to JISK-5400 standard method test, the best is 6H, followed by 5H, 201209109 4H, 3H, 2H and 1H), and gray gain measurement (using TOPCON Luminance ColorimeterBM7 as the measuring instrument, the central luminance unit is Cd/m2) 'The results are shown in Table 2 below: Table 2 Formulation group Abrasion index Adhesive pencil hardness Brightness gain value (Cd/m2) Control group 0.163 5B 1H 1.6611 Ml 0.149 5B 2H 1.6524 M2 0.144 5B 2H 1.6548 M3 0.138 5B 2H 1.6556 M4 0.124 5B 3H 1.6512 M5 0.118 5B 3H 1.6533 M6 0.116 5B 3H 1.6526 M7 0.115 5B 3H 1.6508 M8 0.115 5B 3H 1.6516 M9 0.114 5B 3H 1.6506 M10 0.116 5B 3H 1.6496 As can be seen from Table 2 above, the formulation group (Ml~M10) with MPTMS reaction filler added has better wear resistance than the control without MPTMS. For the adhesion, the effect of the formula group added with the MPTMS reaction filler is the same as that of the control group. Regarding the results of the wrong pen hardness test, the pencil hardness of the formulation group with the MPTMS reaction filler added Greater than 2H, as compared to the control group only 1H pencil hardness, preferably having a hardness of performance. It is particularly important to note that M4~M10, which is added to the MPTMS Reactive Filler Formulation Group, has a pencil hardness of 3H, which has met the requirements of the general industry for not requiring a protective film (3H and 4H). 201209109 As a result of the luminance gain value test, the formulation group (Ml~M10) and the control group added with the MPTMS reaction filler can reach the standard of 16 cd/m2 or more, which meets the requirements of the industry.

In addition, the 'former (I) decane compound can cause hydrogen bonding between polymer chains and increase optical coating. The adhesion between the film composition and the substrate can be applied to a substrate having poor adhesion, increasing the range of application. Thus, the present invention increases the surface hardness of the optical film, reduces the addition of the protective film, effectively reduces the production cost, and simplifies the manufacturing process of the optical film. Therefore, the present invention is extremely progressive and conforms to the requirements of applying for an invention patent, and is filed according to law, and the discount bureau has granted the patent as soon as possible. The above has been published in the Wei-Detailed Outline, but it is only one of the preferred embodiments of the present invention.
