Market demand. Miscellaneous extension (four) __ because of its high transparency, it is widely used in a variety of optical applications, which requires the addition of a general chemical resistance and dimensional stability. ·, low haze, excellent one, and the above mentioned physical properties, the arrow ^ ω - 4 + seven, US Patent No. 6,733, 863 Qingzhou Patent No. l178, 075 A1; U78, 〇 75 As mentioned in A1: species 6,482,501 B2, etc. In Europe, the patented film, and coated formula A #(4) has a transparency, a low haze and a fine followed by a thin brewed 'heart (10) fine (four) gram resin, the fine particles have; ^ large ^ minus the compound _ ' Since these nano/submicron are easily agglomerated to form micrometers or i-rays, the nano/submicron fine particles after drying are coated with particles having a very good capacity and slipperiness, thereby affecting the transparency and fog of the poly-film. The so-called optical defect. Xiang, the particles, if applied to the liquid crystal display panel, may also be produced. The type has a low haze ^3,863 5^ and the US patent M_B2. The coating formulation is also known as the 20 micro water class size. The polyester film of the following particles has a slippery function of 0.01^ 〇, including water-based copolymerized vinegar resin, polyurethane resin, and surface energy of nano/secondary micro 彳 granules, etc., which are quite large. Fine particles, after coating and drying, are very bulky to form micron-sized 5 1305216 and thus affect the optical properties of the pigmented film. In addition, U.S. Patent No. 6,482,501 B2 adjusts its over-coating liquid to remove particles of 2 (micron or more), and the coating phenomenon is apparent. In addition, this patent also emphasizes that the optical polyester film has quite good heat, "Mesh, ant nature" must contain a considerable amount of (mich ~ ~) polyurethane, its heat resistance is generally worse than the known polyester or acrylic resin, facing the visual obscurity In the liquid crystal display board of Zha, the performance of chromaticity and chromatic aberration (10) is not an appropriate choice. n transparency, haze and slipiness, in addition to (4) film substrate (poyethylene te_halate 'pET) The crystallization (as shown in Figure 1 (4) and the type and content of the micron-sized size lubricant in the film-attached film substrate (Figure 1 lb), another important factor is that it is coated on the film. Coating layer on the substrate. In addition to the resin in the coating layer (as shown in Figure 1, the fine particles are added (as shown in Figure 1 to improve the smoothness of the film, the flatness of the f surface, etc. The transparency of the film is closely related to the surrounding (as shown in Figure 1 After that, there will be a working gap (Vold), etc., such aggregation phenomenon, v〇id and epistasis, haze and slipperiness. In addition, the PET polythroat layer (Fig. 2) must be simultaneously The material of the material (four) film (Figure 2 = ^ optical grade Qianli tree ride (Figure 2, 3) wealth of excellent pick-up, this is the demand for the heart. General poly film film == The acrylic coating layer for LCD materials has a good right connection; == miscellaneous adhesion is difficult; similarly, the adhesion of the silk (4) film surface to the acrylic coating layer for the lcd material Poor, but 庐%丨mi has a good connection.
