More preferably, the invention is characterized in that the coating thickness after drying of the polyoxynitride release layer is between 0.06 and 1.6/zm. Hereinafter, embodiments of the present invention will be described in detail with reference to the embodiments of the present invention. It is obvious to those skilled in the art that these embodiments are only intended to illustrate the invention in more detail, but the invention should not be limited by these embodiments. 7 200815544 In general, polyester or polyoxyalkylene (such as polyethylene terephthalate or

Polybutylene terephthalate) has a low polarity like a dielectric substance (see D.W)

Van Krevelen Properties of Polymers, 3rd edition). Polyurethane polyoxane release film exhibits an electrostatic effect during the detachment operation and protection of the adhesive, which may cause foreign matter to be mixed and manifest unsafe. Since the static electricity is determined by temperature, relative humidity, etc., it is considered that the film will be unstable and aging unsatisfactory with the seasons. Therefore, the peeling release film has optical stability for obtaining an adhesive for electrical and electronic displays and is also prevented from being mixed by the antistatic action in the polyoxynitride release film. Out of the important technical needs of uniformity. For this reason, the inventors have found that a release film having excellent peeling force and good antistatic effect can be produced by using a polymer having a polyoxyalkylene structure having a hydroxyl group and a hexenyl group. According to the present invention, when a pulverized film is produced, the film is uniformly coated with a polysulfide, and the formed film can be used in various release film fields, such as a polarizing film for producing a multilayer. Ceramic carrier (黯) carrier release film, LCD protective release film, overlying film, medical therapy, (4) protective film, electrocardiogram, etc., which have different effects from traditional release film, as all A high-grade film of the type of release film market, the release film of which is composed of 20 films. According to the present invention, the polyoxyxane release type of the embodiment of the invention is an excellent antistatic package.

The composition of the Pi material (the oxime-separating liquid,) contains 4·5 to 3 〇 匕 匕, silly% is the host 30% ΐ% of the hydroxy-containing polyoxy siloxane solid material, 0·3 Hydrogen polyoxyalkylene in the hexanyl group of 3 s 丞 0.00 0.00, 0.002% to 8 200815544 0.005% platinum catalyst, and the rest is water. The average size of the solid material of the hexenyl polyoxyalkylene is grade. The polyoxyalkylene release liquid can be directly applied to a film formed of polyester, polypropylene, polyethylene, polyethylene, nylon, polycarbonate, plastic, kraft paper, non-woven fabric, cloth, or the like. Preferably, the solid material in the composition is present in an amount of from 4.5 to 30% by weight, more preferably from 6 to 20% by weight. If the content of the solid material is less than 4.5% by weight, the formed film exhibits problems in uniform coating (covering), and also has poor physical properties in detachment and peeling. If it exceeds 3 〇 10% by weight, the content of the solid material in the release liquid increases, resulting in an increased viscosity. Therefore, the formed film exhibits problems such as coating strips and coating defects on the coating. Preferably, the polyoxo igniting liquid has a thickness of from 0.04 to 2.0 g/m 2 , more preferably from 0.06 to 1.6 g/m 2 , of a dry polysiloxane concentration. The following chemical formula 1 is a hydroxyl group-containing hexenyl polyfluorene in a polysecond oxygen-burning liquid composition of an embodiment of a polyoxyalkylene-separated plastic film having excellent antistatic properties according to the present invention. The structure of oxyalkylene.

CHS H CHS In the above chemical formula, m, n, p, q and r are equal to or greater than 5 integers. Furthermore, the r/m system is in the range of 1.2 < r/m < 2.5, and further, η /p > 3 needs to be satisfied. When r/m is less than 1.2, it has a problem in curing. When it is more than 2.5, the unreacted hydrogen polyoxyalkylene which is cured after the polyoxyalkylene layer is cured reacts with an adhesive such as propylene, and thus, the reaction causes an increase in peeling force. When n/p is less than 3, the antistatic effect on the formed film becomes dominant, thus obtaining a coating film having a peeling force greater than that of the desired one. Further, when a release liquid which is a polyoxyalkylene-separated plastic film having excellent antistatic properties according to an embodiment of the present invention is applied, the plastic film can be applied to the unstretched sheet. A uniaxially stretched film of corona or plasma treatment, or a biaxially stretched film treated by corona or plasma, or treated with corona or plasma immediately prior to biaxial stretching at 15 o'clock. Substrates such as polyester, polyethylene, polypropylene, nylon, polycarbonate, polyvinyl chloride, PVA, and the like. [Example 1-3] Each of Examples 1 and 3 will be exemplified by a polyanthmized release film having an antistatic property as shown in the following Table 1. In these examples, (4) having the structure of the above chemical formula was used, and the in-line coating (〇atlng) was fine during the production method of the poly(tetra). In-line coating on intaglio: wire rod, grooved, comma, MpG (multi-pressure gravure) 3, 6 dry coating is applied without causing any problems. Furthermore, it is also possible to control the thickness of the coating by the mesh type of the Japanese type. The test towel-like substrate was developed into a B-sheet having a surface characteristic similar to that of the commercially available XD5〇〇_38_ for the t〇raysaehanmlcc release load. At 10, in order to manufacture a "B sheet", "A sheet" is first produced by plasticizing a poly-polymerized section by a poly Lai manufacturing method, and then cooling it to a non-, crystalline, crystalline sheet. Then, the enamel sheet is obtained by stretching the Α sheet in the longitudinal direction. On the formed B sheet, the in-line coating is applied, and the coating method is coating coating 10, 8. 6 wt% of a solid material of hexenyl polyfluorene oxane containing a hydroxyl group and a hexenyl group (individually for Examples 1, 2 and 3), 1% by weight of hydrogen polysulfide, 〇·003 The platinum catalyst of %, and the remaining polyoxane deionized liquid of water. The thickness of the coating after drying of the polyoxynitride release layer is 〇·12 μιη. [Comparative Example 1-3] Comparative Examples 1 to 3 A polyoxyalkylene release plastic film produced in the same manner as in the examples 1 to 3 except that it is manufactured under the conditions shown in Table 1. Thereafter, it is applied to the practice according to the present invention. The experimental examples of the examples and the comparative examples will be explained in more detail. [Experimental Example] 11 200815544 The cured film of the tape stripping force coated with polyoxyalkylene is coated with polyoxyalkylene oxide. The surface tape TESA 7475 was combined and combined. A 70 g/cm 2 iron rod was placed on the combined release film and maintained at 23T: and 50% RH for 24 hours. Then, 5 its peel force was obtained from Chemlnstrument Co. The AR1000 was measured three times at a peel angle of 180 degrees and a peel speed of 0.33 m/min. Then, the measured values were averaged. The rubbed after aging was coated with a polysiloxane and obtained from JEIOTECH Co. Thereafter, the crucible 180 was maintained at 10 50 ° C and 95% RH for 3 days. Then, it was strongly rubbed off with a finger to test the rubbing property of the polyoxyalkylene layer on the polythene film, and then the cured polyoxyalkylene was examined. Adhesion between PET film and surface film. The surface resist release film was maintained at 23 ° C and 60% relative humidity for 8 hours to evaluate the antistatic effect with a surface 15 resistance measuring machine, and the surface resistance was expressed in Ω / □. Adhesiveness The adhesive ratio of your residue is a method of measuring the degree of cure of the polyoxyalkylene layer. After the tape is attached to the layer coated with polyoxymethane, the tape is removed after a certain time has elapsed. Then, the tape is attached to the film that has not been treated In order to check the adhesion change of the tape, here, if the residual adhesive ratio is 95%, it means that for 5%, the polyoxoxime is transferred without any reaction. 12 200815544 [Table 1] Adhesive ratio of surface condition peeling force Surface resistance peeling force, surface resistance n/pr/m Solid material (weight) Coating thickness Example 1 13 1.5 10 0.12 15.5 95.4 3·2*10Λ8 ◎ Example 2 13 L5 8 0.08 233 95.7 5.7*10Λ9 〇Example 3 13 1.5 6 0.06 27.8 94.8 7.2*10Λ9 〇Comparative Example 1 8 3 8 0.08 75.4 97.8 1·3*10Λ8 ▲ Comparative Example 2 8 3 6 0.06 83.8 97.5 2·5*10Λ9 ▲ Comparative Example 3 2.5 3 10 0.12 354.3 98.0 4·7*10Λ7 ▲ Note ◎ excellent; 〇 is good; ▲ is worse than the above table 1, "solid material (% by weight) " indicates polyoxane separation

In the composition of the liquid type, π contains a solid material of a hydroxy group and a hexenyl group of a hexenyl polyoxyalkylene. 5 From the above Table 1, it can be seen that when the molecular structure of the same polysiloxane described in Examples 1 to 3 is used, the inventors can see that the thicker the coating layer is, the lower the peeling force is. The inventors can also see that the repeating unit m, the higher the r/m value of the hydroxy group repeating unit r contained in the hydrogen polyoxyalkylene and the hexenyl group of the decyloxy group containing the hexenyl functional group, remains. The higher the adhesion ratio. The inventors can therefore see the high reactivity between the hydrogen polyoxymethane and the polyethylene terephthalate and the acrylic tape from the above Examples 1 to 3 and Comparative Examples 1 to 3. The smaller the n/p value (this value is obtained by comparing the dimethyl repeating unit of the hexanyloxy group having a hexenyl functional group with the transradical repeating unit), the greater the peeling force and the antistatic effect. The higher the height. The higher the hydroxyl repeating unit, the higher the antistatic effect, but the peeling force becomes larger. In summary, a suitable amount of solid material can be used in Example 1 to achieve good peel strength and antistatic effect. In Examples 2 and 3, the greater peel force was measured due to a lower amount of coating material than in Example 1. However, Comparative Examples 1 to 3 exhibited unsatisfactory peel strength and antistatic effect as compared with the examples. Furthermore, in the manufacture of a continuous biaxially stretched film (i.e., applying a coating in the line before the 10th film to be stretched and then coating the film with a wet release liquid), and conventional off-line coating By the present invention, it is possible to reduce the amount of material to be processed. If more steps are included in this processing: in the middle, there is bound to be a higher probability of having a material that is outside. The use of foreign materials in electronic applications can cause serious external defects due to the large peeling force and the transfer of the adhesive layer. By the present invention, an excellent release film can be produced by performing in-line coating with a unique structural formula of the invention described in the application of the present application. It is to be understood that the above-described embodiments are illustrative and not restrictive, and that the skilled artisan can design many additional embodiments without departing from the scope of the invention as defined by the scope of the invention. Optimum Efficacy This product can be used to reduce the amount of dust or foreign materials attached to the polyester film by achieving good antistatic effect and good separation from the moon.
