The optical film of the present invention is required to have a light transmittance of 80% or more at a wavelength of 440 nm. When the light transmittance at a wavelength of 440 nm is less than 80%, the light film in the visible light short wavelength region is cut, so that the optical film itself has a strong yellowish color and can not exhibit excellent transparency. The light transmittance at a wavelength of 440 nm is preferably 85% or more, more preferably 90% or more.
The optical film described in the present invention means, in flat panel display applications, a polarizer protective film or a retardation film constituting a polarizing plate, various surface treated films located on the front of a display having anti-glare or clear hard coat, and other luminance improvements A film, a viewing angle improvement film, a transparent conductive film etc. are mentioned.

紫外線吸収剤は、一般的に380nm以下の波長領域の紫外線を吸収する能力に特化しており、紫外線領域と可視光領域の境界近傍(380〜400nm付近)や、可視光短波長領域(400nm〜430nm)の光線を吸収する能力は優れていない。そのため、紫外線吸収剤を含有させることのみで、紫外線領域と可視光領域の境界近傍(380〜400nm付近)や可視光短波長領域(400〜430nm)の光線をカットするためには、後述する一部の長波長紫外線吸収を除いて、高濃度に含有させる必要がある。紫外線領域、および、可視光短波長領域(380nm〜430nm)の波長カットを、単独の紫外線吸収剤により達成可能な紫外線吸収剤としては、あくまで一例であるが、市販の紫外線吸収剤としては2−(5−クロロ−2H−ベンゾトリアゾール−2−イル)−6−第三ブチル−4−メチルフェノールや、2,4,6−トリス(2−ヒドロキシ−4−ヘキシルオキシ−3−メチルフェニル)−1,3,5−トリアジンの構造で記される化合物などが挙げられる。
Ultraviolet absorbers are generally specialized in the ability to absorb ultraviolet light in the wavelength range of 380 nm or less, and in the vicinity of the boundary between the ultraviolet range and the visible light range (approximately 380 to 400 nm) or in the visible light short wavelength range (400 nm to 400 nm) The ability to absorb light at 430 nm) is not good. Therefore, in order to cut light in the vicinity of the boundary between the ultraviolet light region and the visible light region (approximately 380 to 400 nm) or in the visible light short wavelength region (400 to 430 nm) only by containing the ultraviolet light absorber, It needs to be contained in high concentration except for long wavelength ultraviolet ray absorption of part. The UV absorber capable of achieving wavelength cutting in the ultraviolet region and the visible light short wavelength region (380 nm to 430 nm) with a single ultraviolet absorber is merely an example, but as a commercially available ultraviolet absorber, (5-chloro - 2H-benzotriazol-2-yl) -6-tert-butyl-4-methylphenol, 2,4,6-tris (2-hydroxy-4-hexyloxy-3-methylphenyl)- The compound etc. which are described by the structure of 1, 3, 5- triazine are mentioned.

熱可塑性樹脂をペレットなどの形態で用意する。ペレットは、必要に応じて、熱風中あるいは真空下で乾燥された後、押出機に供給される。押出機内において、融点以上に加熱溶融された樹脂は、ギアポンプ等で樹脂の押出量を均一化され、フィルター等を介して異物や変性した樹脂などが取り除かれる。これらの樹脂はダイにて目的の形状に成形された後、吐出される。そして、ダイから吐出されたシートは、キャスティングドラム等の冷却体上に押し出され、冷却固化され、キャスティングフィルムが得られる。この際、ワイヤー状、テープ状、針状あるいはナイフ状等の電極を用いて、静電気力によりキャスティングドラム等の冷却体に密着させ急冷固化させることが好ましい。また、スリット状、スポット状、面状の装置からエアーを吹き出してキャスティングドラム等の冷却体に密着させ急冷固化させたり、ニップロールにて冷却体に密着させ急冷固化させたりする方法も好ましい。
このようにして得られたキャスティングフィルムは、つづいて長手方向および幅方向に二軸延伸されることが好ましい。延伸は、逐次に二軸延伸しても良いし、同時に二軸延伸してもよい。また、さらに長手方向および/または幅方向に再延伸を行ってもよい。
Next, the preferable manufacturing method of the optical film of this invention is demonstrated below. Of course, the present invention is not construed as being limited to such examples.
The thermoplastic resin is prepared in the form of pellets and the like. The pellets are supplied to an extruder after being dried in hot air or under vacuum if necessary. In the extruder, the resin is heated and melted above the melting point is uniform the extrusion amount of the resin with formic A pump or the like, or a foreign object denatured resin are removed through a filter or the like. These resins are molded into a desired shape by a die and then discharged. Then, the sheet discharged from the die is extruded onto a cooling body such as a casting drum and cooled and solidified to obtain a casting film. Under the present circumstances, it is preferable to closely_contact | adhere to cooling bodies, such as a casting drum etc., by electrostatic force using a wire-like, tape-like, needle-like or knife-like electrode, and to make it harden rapidly. It is also preferable to blow air from a slit-like, spot-like or plane-like device to adhere closely to a cooling body such as a casting drum to cause rapid solidification, or to closely adhere to a cooling body with a nip roll to cause rapid solidification.
It is preferable that the casting film thus obtained is subsequently biaxially stretched in the longitudinal direction and the width direction. The stretching may be sequentially biaxially stretched or may be simultaneously biaxially stretched. In addition, re-stretching may be performed in the longitudinal direction and / or the width direction.
