The stalk of the month is a polyethylene-based film made of a film-forming material containing 201206959 leaven resin (A), and 痄〇^=3 〇 (: water for 5 minutes, the width of the width (TD) direction of the swelling = the ratio of the degree of swelling (XMD) of the sufficient direction (xtd / xmd) is 10 = 7 in addition to the poly (10) alcohol The method for producing a film is to provide a polarizing film composed of a ruthenium film of the present arm, and a right polarizer. The polarizing plate composed of a hait is provided with a protective film on at least one side of the slanting shirt, and is known to be manufactured in Polyethylene County. At the time of film formation, a polyethylene glycol-based resin is formed into a film, and dried and processed using a plurality of hot-rolled sheets. The direction forms a certain degree of tension, and the city time yields a shrinkage in the direction of ^(TD). The obtained polyethylene glycol film has a large degree of swelling in the water and a width in the width (TD) direction, and as a result, the width is two. When the width is small, the swelling degree in the width direction is large. When the film is not uniformly swelled, the dyeing is uneven or unevenly spread. Therefore, in the present invention, as described above, the occurrence of unevenness is focused on polyethylene. The swelling of the mesial film is a predetermined degree of swelling ratio which is smaller than that of the conventional film. [Effect of the Invention] The polyvinyl alcohol of the present invention is excellent in extensibility and has an effect of obtaining a dyed film. And the "polyvinyl alcohol-based film" is used as a raw material film for a polarizing film such as a liquid crystal display device such as a liquid crystal display device such as a liquid crystal display device, and the raw material film of a wave plate or a quarter wave plate. A raw material film for a phase difference amine for liquid crystal display sighing is very useful. [Embodiment] The present invention will be described in detail below. The polystyrene film is a film containing a polyethylene resin (4). The polyethylene film used for the film formation, the ratio of the swelling degree (Xtd) in the width (10) direction and the 201206959 swelling degree (Xmd) in the machine direction is immersed in the water for 5 minutes. (The following is abbreviated to the case of 4 "swelling ratio".) / ) The degree of swelling in the machine (MD) direction and width (TD) direction refers to the width of the water impregnated at 3 ° C for 5 minutes ( The elongation in the TD direction and the elongation in the machine direction were measured as follows. In detail, the film is cut into a square of l〇cmxl0cm, which is parallel to the direction of the surface (Μ〇) and the width (TD), and placed on a flat glass plate to measure the MD direction and The size of the wide TD direction. Then, after being immersed in the ion exchange tank adjusted for 5 minutes, the film was taken out and immediately placed on a flat glass plate to measure the MD direction and the width TD direction of the ruler and the ίί (4) direction system and area by the vernier caliper.

The Z-I is used to obtain a film forming material having a concentration of 鸠, and the aqueous solution (liquid temperature: 14 Tt) of the material is supplied to the double. Axis sowing 22 201206959 machine 'and defoaming. The film forming material after defoaming is formed by the tube type; straight manif0ld die) is rolled from the T-slot die (straight shape and film formation. At this time, the system The gap opening degree of the hot rolling report using the τ-type slit mold is called the casting, and the gap opening degree is larger than the black portion of the center portion to 15 〇. The conditions for the casting and forming film are as follows: 4 degrees ^. Report (hot rolling pro: R1) straight shuttle: 3200mm, width: 4 3m, green hemp, occupies; thief, τ modulo σ simple fat temperature: 9; ^ degrees: 8m / min, surface temperature: ί ΐ Rolling, the percentage of film moisture at the time of peeling off was π%. Pro, at the same time, i line drying, the front and back sides of the film are passed through the dry rolling. ^ Drying and rolling the first to the fifth (hot roll: 94〇c diameter: 320 positions, width: coffee Rotation speed: 8111/min, surface temperature: •= 6th to 10th of the rolling wheel (hot roll: R7~ru) 75t牷: 32〇_, width: 4.3m, rotation speed: 8m/min, Surface temperature: 丄 After sampling and drying, the film 'measurement film moisture percentage is 12%. The suspension Si machine is the next step, by blowing the warm air film from both sides of the film. The width of the film is called the thickness of the film. The physical properties of the polyb-baked alcohol-based film obtained by the polyvinyl alcohol of 63 μm are shown in Table i. The polyvinyl alcohol-based film of the present invention obtained in the following paragraph was obtained by the following method and was subjected to the following The evaluation results are shown in the table. The station can be immersed in the water tank at a water temperature of 3G ° C while being immersed in the water from the iodine 0'2g, L, Potassium iodide ❿8, ''糸 color trough (30 C) for 240 seconds, one side extended to 1.3 times, and immersed in a boric acid treatment tank of 50 g / L, potassium iodide 3 〇 g / X (5 〇 art At the same time, it was extended to 3.08 times, and it took 5 minutes to carry out rotten acid treatment. After that, 23, 2012,069,059 lines were dried, and a polarizing film having a total stretching ratio of 6 times was obtained. <<Uneven evaluation of dyeing unevenness>>; ' On both sides of the polarizing film obtained as described above, a binder is used, and a polarizing plate obtained by laminating the tri-system aqueous solution is used as a polarizing plate. The polarizing plate is self-producing a bismuth film and a bismuth film at 50°. In the C sample, the knife was fixed at a width of 2 mm in the width (TD) direction, and the difference between the minimum and the 値 is 20 cm x 2 〇 cm. The uneven dyeing was evaluated. The father's winter penetration rate, the maximum 値, the patriarchal permeability In the production of the poly-film obtained by the above-mentioned method, Further, the elongation limit material was measured until the breakage of the film was determined, and the film was formed by the film of the film of Example 2 and 3, and Comparative Examples 1 and 2. The condition was changed to the same as that shown in Table ,, and was carried out in the same manner as Λ, to obtain a poly-Beneze film, and The same procedure was carried out to obtain a polarizing film. The obtained polyethylene film and polarizing film were evaluated in the same manner as in Example 1. The evaluation results are shown in Table 1.
