Poly (methyl methacrylate) (PMMA), poly(ethylene terephthalate) (PET), polycarbonate (PC), and polyethersulfone (PES) can be fabricated into transparent films and replace the glass substrates of heavy weight and fragility.（塑料基材可制成薄膜，重量轻且不易破碎）Plastic products are replaced glass products because of their workability and light weight. However, the surface of such plastic products do not resist scratches. Therefore, a hard coat film is often applied to their surfaces to impart scratch resistance thereto.In addition, Conventional glass products are frequently covered with a plastic film to prevent shattering, To improve the surface hardness of such a plastic film, a hard coat layer is generally formed on the surface of the plastic film.5塑料薄膜发展方向：? 材料保护? 功能化? 装饰性Also, if various functionalities are given to the surface of plastics, including anti- glaring (defogging), water repelling (water shedding), anti-stain (prevention of fouling on the surface), etc., it can not only enhance the level of product’ s features, but also create more new products with notable features.塑料表明赋予防眩、防雾、防水、防污等功能，不仅可提供产品性能，还可创造新产品。6Hard Coat Film is usually used as a protective layer for the surfaces of displays such as FPD (such as LCDs, PDPs, FEDs, and organic EL devices), touch panels of home electric appliances, glass, and the like and also relates to a hard coat film used as a protective film therefor.硬化膜一般用于平板显示器（LCD、PDP、OLED等）的表面保护7Anti-Scratch Hard Coat Film Basic Requirements (Key Technology )High pencil hardness, anti-scratch（高铅笔硬度，耐划伤）Strong adhesion on substrates (base films) （对基膜附着力优异）Low Curl (Low Shrinkage)（低卷曲（低收缩））High TT (Total Transmittance) and Low Haze（高透光率，低雾度）Smooth surface (Without Surface Crystal Phenom
