    • A method for producing optical films is provided which comprises the steps of: melt-extruding a thermoplastic resin into a film through a die of an extruder, pressing the melt-extruded thermoplastic resin layer together with a supporting layer between a cooling roll which is made of metal or ceramic and a rubber roll which is pressed against the cooling roll and rolled in the same circumferential direction, carrying the thermoplastic resin layer together with the supporting layer under taking off tension until the thermoplastic resin layer is cooled down, and peeling and separating the supporting layer from the thermoplastic resin layer to obtain a thermoplastic resin film. Optical films are provided by a melt-extrusion method which have less optical surface defects such as die lines and gear marks and less fluctuations in film thickness and have uniform optical characteristics, which are useful as a material for various optical films used in liquid crystal displays, especially, a retardation film.
    • 提供一种光学薄膜的制造方法,其特征在于,包括以下步骤:通过挤出机的模头将热塑性树脂熔融挤出成膜,将熔融挤出的热塑性树脂层与支撑层一起在制成的冷却辊之间 的金属或陶瓷以及橡胶辊,其被压靠在冷却辊上并在同一圆周方向上滚动,在脱模张力下将热塑性树脂层与支撑层一起承载直到热塑性树脂层被冷却,并剥离和分离 从热塑性树脂层得到支撑层,得到热塑性树脂膜。 通过熔融挤出法提供光学膜,其具有较少的光学表面缺陷,例如模具线和齿轮标记,并且膜厚度的波动较小,并且具有均匀的光学特性,其可用作用于液晶显示器的各种光学膜的材料 ,特别是延迟膜。
