INSTRUCTIONS: [Technical Fields of the Invention] The present invention relates to an aqueous coating liquid formulation which can be applied to a polyester film (substrate), and can be coated with an ester film after the coating. (Substrate) has high transparency, low haze, excellent adhesion, and slip properties, and is suitable for applications such as diffusion films, brightness enhancement films, antireflection films, and protective films for LCDs (or CRTs). Polyester film for use. [Previous technology] In the years of continuous improvement and breakthrough in technology, 3C products have been widely used in people's lives, such as portable notebook computers, LCD TVs, etc., and then drive the market of liquid crystal display panels. demand. Because of the high transparency of the film, the biaxially stretched film has a high degree of transparency, so it is considered to be a film for various optical applications. In addition to the need to have the chemical resistance and dimensional stability of the film. Sexual β#ΐίϊ has high transparency, low haze, excellent adhesion and slip properties, and is generally coated on a polyester film (as shown in Figure 1 on one or both sides of the d (Figure 1 Mei ^ specializes in 6 ^ physical properties, previously related technologies such as European Patent No. U78,075 A1; i 1 - ^ ° « Membrane, which coats you West F ancient k ^, has translucent, low haze and excellent Poly vinegar thin 001 ~ 〇, 3: The two commonly known ingredients, including water-based poly s-resin resin, acrylic resin, micro-lining Qiansi rectification, due to this recorded rice / sub-micron easy to reunion The surface energy, after coating and drying, the nano/submicron fine particles are very accommodating, and the grain of the rice size 'in turn affects the transparency of the polyester film, the so-called light of the mist. The particles of the agglomerated 'is applied to the liquid crystal The display panel will probably produce a number and also mention a 22, 6'^3, 863 B1 and the United States Patent No. 6,482,501 Β2, the coating formulation is also a Wei film containing particles under the 2G micron scale phase, with the age of slippery function, the cocoa copolymerization_lipid, the polyhedral resin and the surface energy. .I=m fine particles, etc., in the same way, these have relatively large particles in the formulation, and they are very agglomerated after coating to form the optical properties of the micron-sized "KS-bonded film." U.S. Patent No. M82,5〇1B2 No. 5 200808892 particularly emphasizes that the use of a filter coating solution to remove particles larger than 20 microns, it is obvious that the coating liquid should be agglomerated, and the patent also emphasizes optical polyester. The film has quite good thermal stability, but the composition must contain a considerable amount (10~9〇%) of polyurethane component, which is resistant to UV light or heat resistance - like conventional polyester or acrylic In the face of visually demanding liquid crystal display panels, the performance of chromaticity, chromatic aberration and other characteristics is not an option. - Generally speaking, the fine film is transparent, hazy and miscellaneous, except And the film substrate (pdye%lene terephthalate 'referred to as P The crystallization of ET) (as shown in Figure 1 (4) and its pE butyl film, plus the type and content of the micron-sized size lubricant (Figure 1), another important factor is the coating on the polyester film. Coating layer. In addition to the resin in the coating layer (as shown in Figure 1, fine particles are added as usual (see Figure 1 for improving the slipperiness of the poly-film, and at the same time, the rate of incidence, surface flatness, etc.) It is closely related to the penetration of the PET film, and the layer of the tester (such as 2b), if it is charmed, it will be produced around it after it is lightly stretched. The film is transparent, bumped and miscellaneous. Correction, on the PET film coating layer two coating layer (Figure 2, 2) must be on the substrate of the polyester film (Figure 2 D and the coffee The optical grade acrylic resin coating layer (Fig. 2, 3) has excellent adhesion: the demand for & -General poly (four) coating on the surface of the film =
