In the text, 'X and Y are integers greater than zero, and the total number of χ and γ is preferably less than or equal to 230. If it is higher than 230, the compatibility of the surfactant may be deteriorated, so that problems such as deterioration of pinhole resistance may occur. In addition, the surfactant must have good compatibility with the alkenyl polyoxane. The surfactant is preferably used in an amount of from 0.3 to 1 to 5 parts by weight per 100 parts by weight of the dilute polyoxyalkylene, and more preferably the surface tension of the substrate film is 1.0 to 10% of the surface tension of the coating solution 201102415. 1.5 times. If the surface tension of the substrate film is 1_0 times or less the surface tension of the coating solution, the wet property of the coating solution may be deteriorated. If it is more than 1.5 times, internal coagulation occurs in the coating solution, so that after the coating is cured, external defects are caused. Moreover, the polyfluorene ionized coating composition according to the present invention is diluted so as to have a solid content of 1.2 to 5% by weight based on the total coating composition weight, and is coated on the polyester film. on. Although the solvent to be used for coating the composition is not limited, it is limited in that it can disperse the solid component of the present invention so as to coat the coating composition on the polyester film, preferably water. If the solid content of the polyfluorinated ion-off coating composition for the polarizing film is less than 1.2%, a uniform polyoxynitride coating layer is not formed properly, and thus may be generated, for example, after laminating through the adhesive layer The problem of tearing once peeled off. If it is higher than 5%, adhesion occurs between the films and after a certain period of time, external damage of the product and changes in peel strength may occur. Hereinafter, the present invention will be described in detail with reference to the preferred embodiments and comparative examples.

An activator and a 50 ppm platinum chelate catalyst were placed in water to prepare a polyfluorene ionized coating composition having a total solids content of 2% by weight. Then, a composition having a thickness of 10 μm was coated on the surface of the corona discharge-treated polyester film. After coating, the film was heat-treated in a hot air drier at 180 ° C for 20 seconds to produce a polyfluorinated release coating film for a polarizing film. 11 201102415 [Example 2] The same procedure as in Example 1 was carried out except that 3.5 parts by weight of hydrogen polyoxyalkylene per 100 parts by weight of alkenyl polyoxyalkylene was added to produce a polyfluorene ionization type for a polarizing film.

Laminating. [Example 4] The same procedure as in Example 1 was carried out except that 1.5 parts by weight of the surfactant per 100 parts by weight of the alkenyl polyoxyalkylene was added to produce a polyfluorene-separated coating film for a polarizing film. . [Comparative Example] [Comparative Example 1] The same procedure as in Example 1 was carried out to prepare a polyfluorene for a polarizing film, except that 7.0 parts by weight of hydrogen polyoxyalkylene per 100 parts by weight of alkenyl polyoxyalkylene was added. Oxygen-free coating film. [Comparative Example 2] The same procedure as in Example 1 was carried out except that the surfactant was not added to produce a polyfluorene-separated coating film for a polarizing film. [Comparative Example 3] The same procedure as in Example 1 was carried out except that 2.0 parts by weight of the surfactant per 100 parts by weight of the alkenyl polysiloxane was added to produce a polyfluorene-separated coating film for a polarizing film. 12 201102415 The physical properties of the films prepared in the above Examples 1 to 4 and Comparative Examples 1 to 3 (abbreviated as Comp· Ex. 1 to 3 in Table i) were tested as follows, and the results are shown in the table. 1 inside.

The surface tension. <Surface Tension of Substrate> Test solution for surface tension (formamide) was applied according to the standard procedure of ASTM D2578, from a test with a lower surface tension, a solution of gluten to a test solution having a relatively high surface tension. a mixture of ethylene glycol and diethyl ether). The results show that the test solution for surface tension has a good wet shape and takes at least two seconds. [Test Example 2: Determination of peel strength] - Preparation of test sample 1 The test sample on which polysulfide was coated was stored at 25 ° C and 65% RH, and it took 24 hours. 2 Adhere the standard tape (TESA7475) to the coated polyoxo side of each test sample, and then press each sample at room temperature (25 ° C) with a load of 20 g / cm 2 for 1 day. And 14 days to determine the physical properties. - Measurement equipment: Chem-instrument AR-1000 - Measurement method: 1 Peeling angle: 180°, peeling speed: 12 inches/min. 13 201102415 2 Sample size: 500 mm X 1500 mm, used for peel strength measurement Size: 250 mm X 1500 mm. - Measurement data: The unit of peel strength is in grams per inch, and the measured value is the average of 5 measurements.
