[Embodiment] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail. As described above, an antistatic coating composition according to the present invention comprises 15 • a conductive polymer aqueous dispersion solution; a water soluble binding resin; an alcohol solvent; a functional organic solvent; water; Coagulant. The conductive polymer is used to impart a antistatic property to a surface of a coated film, thereby removing contaminants (e.g., dust). In the 20 coating composition of the present invention, the conductive polymer aqueous dispersion solution is obtained by dispersing or dissolving a conductive polymer compound in water, and the concentration of the conductive polymer compound is 0.1 to 10 wt% based on the total weight of the aqueous dispersion solution. The conductive polymer compound may be a polythiophene, polypyrrole, or polyaniline-based polymer compound. A polythio 8 200823270 pheno-based compound is preferred. P〇lyethylene dioxythioPhene (PEDOT) is particularly preferred. Regarding the conductive polymer aqueous dispersion solution, a commercially available Baytron P or Baytron PH manufactured by Bayer can be used. Baytron 5 p is a product obtained by adding polystyrenesulfonic acid (pss) as a dopant to a PEDOT dispersion solution in water. The PED0T content in Baytron P is approximately 1.4%. The content of the conductive polymer aqueous dispersion solution is preferably from 1 to 3 % by weight based on the total weight of the coating composition. If the content of the conductive polymer 10 aqueous dispersion solution is less than 1% by weight, the surface resistance of a coated film may be increased, thereby reducing an antistatic effect. On the other hand, if the content of the conductive polymer aqueous dispersion solution exceeds 30% by weight, the coating property of the coating composition can be lowered, accompanied by no significant improvement in antistatic and electromagnetic interference shielding functions, and The preparation cost of the coating composition 15 may be increased. In the antistatic coating composition of the present invention, the water-soluble binder resin functions to improve the dispersibility of the conductive polymer and the uniformity, adhesion property, strength and the like of a coating film. The water-soluble binder resin may be selected from many types of common photocurable or thermosetting binder resins. Examples of the water-soluble 20-bonding resin include, but are not limited to, polyamine phthalate, polymethyl methacrylate, polyacrylic acid, polyvinyl alcohol, polyvinylacetal, polyvinyl acetate, and the like. mixture. Among them, a water-soluble thermosetting polyurethane resin is preferred because a coating film formed of the water-soluble thermosetting polyurethane resin can have good adhesion properties and strength. Characteristics, as well as antistatic properties. The content of the water-soluble binder resin may be 5 to 25 wt% based on the total weight of the coating composition. If the content of the water-soluble binder resin is less than 5 wt%, the uniformity, adhesion property, and strength of a coating film may be reduced by 5. On the other hand, if the content of the water-soluble binder resin exceeds 25 wt%, the dispersibility of the conductive polymer can be lowered, thereby lowering the antistatic property of the coating film. When the coating composition is applied to a large area, stains may be frequently caused. In the antistatic coating composition of the present invention, the alcohol solvent acts to improve the coating properties (including drying properties) of the coating composition. The alcohol solvent may be selected from a wide variety of alcohol compounds which are generally used in polymer coating compositions. Preferably, the alcohol solvent may be at least one selected from the group consisting of aliphatic alcohols having 1 to 5 carbon atoms. "A mixture of ethanol, isopropanol, or the like is preferred.

The alcohol solvent may be present in an amount of 5 to 4 G wt%, preferably The ground 1 〇 to 3 〇 1 ' is based on the total weight of the coating composition. If the alcohol solvent is less than 5 wt%, the drying property of the coating composition may be lowered. If the content of the alcohol solvent exceeds 40% by weight, the dispersibility of the conductive 2-isomer polymer may be lowered, thereby increasing the surface resistance of a coating film. The antistatic coating composition of the present invention includes a functional group. The organic solvent and the aliphatic alcohol solvent further improve the solubility, dispersibility, drying property, and film consistency of the coating composition. The official 10 200823270 energy organic solvent may be two Methotrexate (DMSO), propylene glycol methyl ether (PGME), N-methylpyrrolidone (NMP), ethyl-3-ethoxypropionate (EEP), propanol-acetic acid g (PGMEA), Butylcarbitol (BC), or a mixture thereof, is preferred. Dimethyl sulfoxide is preferred. 5 The content of the functional organic solvent may be 5 to 30 wt%, preferably 1 to 30 wt% 'based on the total weight of the coating composition. If the content of the functional organic solvent is less than 5 The coating property of the coating composition may be reduced, thereby forming a non-uniform film. On the other hand, if the content of the functional organic solvent exceeds 3% by weight, the coating composition 10 The drying property may be reduced, with no significant improvement in coating properties. The antistatic coating composition of the present invention comprises a polymer anti-agglomerating agent which prevents polymer agglomeration occurring on a metal surface. The polymer anti-agglomerating agent herein comprises at least one selected from the group consisting of amine compounds, that is, ethylenediamine, dimethylethylenediamine, 2-15 butylamine, diethanolamine, benzotriene嗤, benzopyrene 嗤, σ ratio σ, toluene three-nose 'porphyrin, imidazole, benzimidazole, 5-methyl-1 fluorene-benzotriazole, polyvinylpyrrolidone, and hydrazine-phenylthiourea The content of the polymer anti-agglomerating agent may be (1) (8) 丨 to (7) wt%, based on the total weight of the coating composition. If the amount of the polymer anti-agglomerating agent is less than 0. 001% by weight, the addition efficiency of the polymer anti-agglomerating agent may be It is insignificant, and thus, the phenomenon of polymer agglomeration cannot be effectively prevented. On the other hand, if the content of the polymer anti-agglomerate exceeds 1 〇wt〇/〇, the dispersibility and antistatic properties of the coating composition are The polymer anti-agglomerating agent may be dissolved in a solvent and introduced into the other components in accordance with 11 200823270. Optionally, the polymer anti-agglomerating agent may also be introduced in addition to the Within a mixture of other components than the polymeric anti-agglomerating agent. When the coating composition is prepared by successively mixing the components described above, water may be added to disperse the water-soluble binding resin and the conductive polymer aqueous dispersion solution.

如自以上的表2能看見的，由於聚合物抗凝聚劑的存 5 在，實施例1 -7的塗覆膜展示出良好的塗覆性質以及沒有聚 合物凝聚，在與比較實施例1_2的塗覆膜相比之下沒有在表 面電阻任何顯著的增加的情況。實施例1-5的塗覆膜展示出 特別優良的抗凝聚作用，由於三乙醇胺，2-丁胺，嗜琳， 苯并三唑，和聚乙烯吡咯烷酮的各別地使用作為聚合物抗 10 凝聚劑。 像比較實施例2的塗覆膜一樣，當一種聚合物抗凝聚劑 的含量增加，表面電阻增加，藉此降低一種抗靜電性質以 及一種塗覆組成物的分散性是降低的。 如上說明的，當使用一種如本發明之抗靜電塗覆組成 15物製備一種抗靜電塗覆膜時，發生於一種塗覆機器的一種 金屬部件之聚合物凝聚現象能被有效地移除，藉此提高一 16 200823270 種塗覆作業的效率和生產力。 因此，一種依據本發明而製備的抗靜電塗覆膜具有良 好的抗靜電性質和透明度以及能被應用至各種各樣的半導 體和顯示工業領域。 5 【圖式簡單說明】 (無） 【主要元件符號說明】 (無) 17As can be seen from Table 2 above, the coating film of Examples 1-7 exhibited good coating properties and no polymer agglomeration due to the presence of the polymer anti-agglomerating agent, in comparison with Comparative Example 1_2. The coated film did not have any significant increase in surface resistance compared to the case. The coated films of Examples 1-5 exhibited particularly excellent anti-agglomeration due to the respective use of triethanolamine, 2-butylamine, lindane, benzotriazole, and polyvinylpyrrolidone as polymer anti-coagulation Agent. Like the coated film of Comparative Example 2, when the content of a polymer anti-agglomerating agent is increased, the surface resistance is increased, whereby the reduction of an antistatic property and the dispersibility of a coating composition are lowered. As explained above, when an antistatic coating film is prepared using the antistatic coating composition 15 of the present invention, the polymer agglomeration phenomenon of a metal member occurring in a coating machine can be effectively removed. This improves the efficiency and productivity of a 16 200823270 coating job. Therefore, an antistatic coating film prepared in accordance with the present invention has good antistatic properties and transparency and can be applied to various semiconductor and display industries. 5 [Simple description of the diagram] (none) [Explanation of main component symbols] (None) 17
