Telephone type computer, etc. The touch panel control mode emphasizes that the user can give instructions in the most intuitive way, that is, directly touch the display screen with a finger, so the operation is ergonomic, but also allows the user to touch the display screen. The probability of the surface increases a lot. Because &, although the touch panel has the advantage of direct and convenient operation, but also because it is easy to touch the panel, it is easy to leave foreign materials on the display screen, such as water marks, fingerprints, dust and oil, etc.: When the naked eye is displayed to show the honor screen, it will affect its visibility due to the stain on its surface. In addition, the color 'sometimes even (4) the surface may be dirty and the signal may be output and manipulated to the electronic The problem of the overall reaction speed of the product. The electronic products with this touch panel are used to solve the above problems. When applied to various electronic products, the display screen is directly in contact with the user 201249904. s # ^ , it is necessary to be applied to an anti-fouling surface treatment. 'Let the surface of this shape __曰一, a coating film with anti-fouling effect, making dirt difficult to contaminate = easy to clean, but the 杬π effect of the coating film currently formed on the surface of the display device still needs to be improved, in addition, The hardness of the film is also considered to be 'to reduce the chance of being scratched. Therefore, there is still a demand in the industry for how to obtain a coating film having a good antifouling effect. SUMMARY OF THE INVENTION Therefore, the first object of the present invention is to provide a coating film having a good antifouling effect.

A fourth object of the present invention is to provide a method for detecting the stain resistance of a coating film. The method for detecting the stain resistance of a coating film of the present invention comprises the steps of: (a) providing a coating film composed of a cured polyacrylic acid vinegar composition; and (b) dropping water and a brominated naphthalene solution respectively. On the surface of the coating film, and using a contact angle meter to measure the contact angle of the water contact angle with the (tetra) naphthalene, if the pair of water contact angles range from 100 degrees to 180 纟, and the range of the contact angle of the pair of bromonaphthalene is From 65 degrees to 180 degrees, it was judged that the coating film had stain resistance. The effect of the present invention is that the coating film of the present invention has a contact angle with water of a specific value range and a contact angle with respect to bromonaphthalene, that is, the contact angle of the pair of water ranges from 100 degrees to 180", and the pair of desert generations The contact angle ranges from 65 degrees to 180 degrees, which makes it have good stain resistance. The inventors have further developed a polymer capable of forming an antifouling film by discovering the relationship between the specific property and the antifouling property.

Preferably, the polyacrylic acid composition comprises a polyacrylic acid resin, a photoinitiator, a solvent and an additive. The above photoinitiators, solvents and additives may be compounds of the prior art and will not be described again. Preferably, the pair of water contact angles range from 1 to 12 degrees, and the pair of water contact angles range from 1 to 5 degrees to 11 degrees. Preferably, the p-bromonaphthalene contact angle ranges from 65 degrees to 8 degrees; more preferably, the p-bromonaphthalene contact angle ranges from 65 degrees to 75 degrees. Further, the coating film of the present invention is prepared by first mixing the polyacrylate-based composition with a solvent in which the polylactic acid-based composition is dissolved to obtain a coating, and depending on the application, the coating is applied.

」代表未添加，比較例5是直接測試市售膜片，故 配方襴位皆標記「.」。 &表1可知’實施例的塗膜的對水接觸角皆大於100 度且對漠代萘接觸角皆大於65度，因此具有良好的撥水及 撥油特性，也就是說不論其表面上有水性或油性的污潰， 都可以輕易被擦除。然，比較例1與2的塗膜對水接觸角 12 201249904 雖」大於1GG度’但對漠代蔡接觸角皆小於&度導致油 ί生筆所產生的污潰在停留於其表面分鐘後，就無法擦抵 乾淨。至於比較例3至6，不但溴代萘接觸角皆小於65度 ’對水接觸角也都小於1GG &，因此，當油性筆-劃上去 後，立即做擦拭的動作也無法擦除污潰。 綜上所ϋ本發明塗膜實施例皆因為具有特定數值的 對水接觸角與對錢萘接觸角，亦即該對水接觸角的範圍 為1〇〇度180度，且該對漠代蔡接觸角的範圍為度至 180度’而具有良好的抗污性。此外，發明人 性質與抗污性的關係，還進—步可以快速㈣選^形^ “膜的聚丙烯酸酿系組成物與檢測一塗膜是否具有抗污 性，故確實能達到本發明之目的。 准以上所述者，僅為本發明之較佳實施例而已，當不 能以此限定本發明實施之範@，即大凡依本發㈣請二利 範圍及發明說明内容所作之簡單的等效變化與修飾，皆仍 屬本發明專利涵蓋之範圍内。 【圖式簡單說明】 圖1為一剖面示意圖，顯示本發明觸控面板之一較佳 實施例； 圖2為一俯視示意圖，說明擦拭測試時，測試者是如 何於測試樣品之表面上繪製線條；及 疋 圖3為一側面示意圖，說明擦拭測試時，測試者是如 何擦栻測試樣品之表面上的污潰，圖中的箭頭代表其=^ L L·. _^ ^ 13 201249904 【主要元件符號說明】 1……基材 2.......塗膜 3……擦拭桿 4.......圓頭 14The representative was not added. In Comparative Example 5, the commercially available film was directly tested, so the formula positions were marked ".". & Table 1 shows that the coating film of the examples has a water contact angle of more than 100 degrees and a contact angle of more than 65 degrees for the naphthalene, so that it has good water-repellent and oil-repellent properties, that is, regardless of its surface. Watery or oily stains can be easily erased. However, the coating films of Comparative Examples 1 and 2 have a water contact angle of 12 201249904, which is "greater than 1 GG degree" but the contact angle of the Modai Cai is less than & degrees causing the oil generated by the oil pen to stay on the surface minute. After that, you can't wipe it clean. As for the comparative examples 3 to 6, not only the contact angle of the bromonaphthalene is less than 65 degrees, but also the contact angle of water is less than 1 GG & therefore, when the oily pen is drawn up, the action of wiping immediately cannot erase the stain. . In summary, the coating film embodiments of the present invention are all based on a water contact angle with a specific value and a contact angle with respect to the money naphthalene, that is, the range of the water contact angle is 1 degree 180 degrees, and the pair of desert generation Cai The contact angle ranges from degrees to 180 degrees and has good stain resistance. In addition, the relationship between the nature of the inventor and the antifouling property can be further improved by rapidly selecting (4) the polyacrylic acid brewing composition of the film and detecting whether the coating film has antifouling property, so that the present invention can be achieved. The above is only the preferred embodiment of the present invention, and it is not possible to limit the implementation of the present invention by this, that is, the simpleness of the scope of the invention and the content of the invention. FIG. 1 is a schematic cross-sectional view showing a preferred embodiment of the touch panel of the present invention; FIG. 2 is a schematic top view showing a schematic view of the touch panel of the present invention; When the wiping test, the tester draws a line on the surface of the test sample; and FIG. 3 is a side view showing how the tester rubs the stain on the surface of the test sample during the wiping test, the arrow in the figure On behalf of its =^ LL·. _^ ^ 13 201249904 [Main component symbol description] 1...substrate 2.......coating film 3...wiping rod 4.......round head 14
