With excellent features. And improvement of tape peeling force and antifouling property [Prior technology] In recent years, with the progress of industrialization, Shen 1, animal 4 from various electronic and electrical equipment, Beixun communication field and general household goods „ < The disaster caused by the static mine is increasing. 'Qinwang 2 2 ^ ^ θ ° ° · Anti-static of the machine and the industrial site becomes a very important issue. The so-called anti-static snow, timely π η ^ electric system will accumulate in How to discharge the surface of the insulator by appropriate method, in order to ^fr Ψ Α ^ ^ ^, as long as the surface of the product is formed to prevent the accumulation of electricity and discharge, the anti-static layer is particularly flawed, after the adhesion of impurities or dust The manufacturing process of the film, the crucible, and the process of processing the thin crucible will generate a discharge, and the use of the organic binder for the ancient 5 soils in the right step will generate a fire hazard. In the case of a material such as an electric oxygen or an electronic component, it may become a cause of static t π electrostatic damage, so it is necessary to attach antistatic performance to the surface of the film. Anti-static splicing : an internal addition method using an anionic compound of an organic sulfonic acid and an organic phosphate; a method or a cation of a vaporized metal compound: a method of conducting conductive inorganic particles, and a method of coating a low molecular anionic or cationic compound A method of coating a conductive polymer or the like.

The phenomenon of blooming reduces the adhesion between the film and the laminate' is a problem. The method of plating a metal compound is excellent in antistatic property and has recently been widely used for a conductive film. However, since the manufacturing cost is not high, it is used only for a specific use.

However, since the antistatic effect is limited, W cannot be obtained. Surface resistance, due to the antistatic properties of the moisture in the atmosphere and the atmosphere, when the moisture content in the atmosphere is low, the resistance = greatly reduced, the solvent resistance is very poor, and there is a tendency to transfer to other surfaces. Sex is its shortcomings, so its use is greatly limited. Or the development of conductive polymers such as polyaniline H, which are dissolved in water and organic solvents, and the application of I for the electrical properties of the materials to the surface of other molecules of the core are being actively carried out. The latter 2: the general method is to make a doped conductive polymer moxibustion, and apply it to a polyester-containing method in a suitable solvent. At the time of the surface of the knife, it is combined with a suitable binder to remove the mechanical properties of the coating layer or the surface hardness. The electrical property is high - for example, in U.S. Patent No. 4,995,430, which discloses that one of the molecules of 200914505, 3,4-ethylenedioxythiophene, and oxidant, p-benzenesulfonic acid (Ir〇) n (m) ρ-toluenesulfonate) and 3,4_polyethylenedioxythiophene (3,4_p〇lyethyIenedi〇xythi〇phene), which is a conductive polymer synthesized, specifically, 3,4- Ethylene dioxythiophene and p-toluenesulfonic acid were mixed at normal temperature and then heated to produce a blue conductive polymer 3,4-polyethylenedioxythiophene.

'So a small amount of reaction inhibitor, imidazole, is mixed to prevent it. A conductive polymer is proposed in Japanese Patent Laid-Open No. _3丨3 52丨, which is obtained by oxidative polymerization of 3,4-dialkyloxythiophene in the presence of a polyanion to obtain poly(3,^dialkyloxythiophene) and A conductive polymer composed of a polyanion having high conductivity, high chemical safety, and high transparency of a coating film at the time of film formation: However, when a coating liquid containing such a conductive polymer is applied to (4) In the case of a substrate, it is not easy to obtain all the properties that can satisfy the adhesion to the substrate, transparency, water resistance, solvent resistance and electrical conductivity. (IV) Membrane: especially in order to improve the water resistance of the coating film. Attempts are made to combine: a method in which a resin is cross-linked by a crosslinking agent, and the like. U.S. Patent No. 6,732,71, based on the purpose of enhancing the adhesion between the conductive polymer layer composed of poly(3,4-di-O-oxynitrene) and polyanion and the adjacent layer, and using epoxy The base of the burnt stone is combined with the water resistance of the coating film. It is difficult to give the above-mentioned antistatic products in various antistatic forms. Recently, 200914505 With the growth of the IT business including the LCD and PDP markets, the demand for antistatic films has increased rapidly. The antistatic film used in this application is the most widely known anti-static form of the cationic ion, and the film using the conductive polymer also enters the market as a high-grade film. The final condition requires excellent antistatic performance and antifouling function, but it is difficult to manufacture in-line coating (in-line (3) to achieve the two functions at the same time as the magical time. Also, depending on the use of the product, when When the protective film is peeled off in the last step, the tape is peeled off by mechanically automatic bonding, but at this time, if the adhesive force between the tape and the antistatic surface is low, the protective film may not be peeled off favorably, or The present invention is directed to solving the above problems, and the object of the present invention is to provide an excellent antistatic polyester film for optical use. The manufacturing method uses conductive molecules to achieve excellent antistatic properties, uses an acrylic resin to enhance the peeling force of the tape, and at the same time adjusts the crosslinking density and improves the resistance/mixability and film properties by using a suitable crosslinking agent. And adding a fluororesin to improve the antifouling function. The method for manufacturing the antistatic polyester film of the present invention for achieving the above object comprises: Stage of axial stretching; stage of producing an antistatic coating liquid containing a conductive polymer resin, an acrylic resin, a crosslinking agent, and a fluororesin; 200914505 One side of the polyester film of the uniaxially stretched a step of applying the coating liquid on both sides to form an antistatic layer; and a step of biaxially stretching the substrate film on which the polystatic layer of the antistatic layer is formed. The antistatic layer, preferably, for conductivity The polymer (4) (10) is composed of an acrylic resin, a blue component, a crosslinking agent, a weight component, and an I resin, 30 to 300 parts by weight.

The crosslinking agent is preferably one or more compounds selected from the group consisting of isocyanate type, some base type, and epoxy type and melamine type. The mouse resin is preferably an antistatic polylactic acid film of the present invention. Excellent antistatic function and even if a proper amount of fluororesin and acrylic resin with antifouling function are mixed, antistatic coating composition is applied to polyester film, I wash with water or ethanol, :hai The antistatic agent of the antistatic layer will not be detached or dissolved, and can have an excellent antifouling function and improve the adhesion with the adhesive tape. The inventors can understand and modify the scope and the scope of the invention. However, the inventions of the present invention can be variously modified within the scope of the technical idea of the present invention. These modifications also belong to the Japanese Patent No. 200914505. [Embodiment] The present invention will be described in more detail below. The method for producing an antistatic polyester film comprises: a step of uniaxially stretching a polyester base film; and producing an antistatic coating liquid containing a conductive polymer resin, an acrylic resin, a crosslinking agent, and a fluororesin. a stage in which the coating liquid is applied to one side or both sides of the uniaxially stretched polyester base film to form an antistatic layer; and the polyester base film on which the antistatic layer is formed is doubled Axial pull Of the stage. Usually, the one side of the polyester film obtained by biaxial stretching is called off-line coating, and the manufacturing process of the above-mentioned polyester film is uniaxially stretched and The application of the coating between the biaxial stretching steps is referred to as in-line coating. The advantage of the in-line coating is that the coating property obtained by the off-line coating step can be ensured in the production process of the polyester film, thereby ensuring the competitiveness without the burden of the manufacturing cost due to the additional coating step. The product. First, the stage in which the polyester base film is uniaxially stretched will be described.

The solvent resistance and coating film properties of the crosslinking agent film used in the present invention are at least one compound selected from the group consisting of a ruthenium-based amide group and a η 唾 琳 。. It is preferable to use an isocyanate type, a % oxygen system, and a melamine type to improve the antistatic layer and the polyester, and the amount of the crosslinking agent added is high with respect to electroconductivity: 100 parts by weight of the resin is added to the crosslinking agent resin in an amount of 1 〇〇 to 1 〇〇〇 by weight. When the amount of the crosslinking agent resin added is less than 100 parts by weight, the antistatic property may be difficult to be exhibited. In this case, the whitening phenomenon occurs due to weak solvent resistance. Further, when it is 1000 parts by weight, the transparency is good, but there is a problem that it is difficult to prevent the antistatic property. Next, the fluororesin will be described. The fluororesin added in the present invention is applied to a polyester ruthenium, which is added to enhance the antifouling property, water contact angle and solvent property of the film, and has polytetrafluoroethylene, Tetrafluoroethylene, perfluoro(alkyl vinyl ether) c〇p()lyme〇, trifluoroethylene, hexafluoropropylene copolymer (Flu〇rinated ethylene c〇p()lymer Propylene cop 〇lymer), ethylene, tetrafluoroethylene copolymer, chlorotrifluoroethylene, ethylene tetrafluoroethylene 13 200914505 copolymer, chlorotrifluoroacetic acid, tetrafluoroethylene copolymer (p〇ly tetra flu) 〇r〇ethylene copolymer), polyvinyl fluoride (P〇ly vinyli flu〇ride), poly vinylidene fluoride, etc., preferably tetrafluoroethylene. On the other hand, the added fluororesin The amount of the fluororesin is 30 to 300 parts by weight based on 100 parts by weight of the conductive polymer resin. When the amount of the fluororesin is less than 30 parts by weight, the antifouling property is lowered, and if it exceeds 3 parts by weight, , the transparency of the film is reduced, and the defense The problem that the electrostatic performance is also lowered is as follows. The above-mentioned antistatic coating liquid of the present invention is preferably produced by coating with respect to the whole; at night, 100% by weight of the 'solid content is 〇5 to 1 〇〇 weight/〇, more The content of the solid component is preferably 〇 5 5 5 。 。 ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ ❶ 1G (% by weight) has a problem that the transparency of the film is lowered.
