摘要:
A process for producing an optical film made of a thermoplastic resin. By the process, a highly transparent film having almost no orientation can be obtained. The process for producing an optical film made of a thermoplastic resin comprises: a molding step in which the thermoplastic resin in a molten state is ejected from a T-die and thereby formed into a film; and a cooling step in which the molten resin formed into a film is pressed between a cooling roll (16) and a touch roll (14) comprising a belt (14a) and a rubber roll (14b) disposed inside the belt (14a) and is thereby cooled and solidified. In the cooling step, the surface temperature of the cooling roll (16) has been set so as to satisfy the requirement shown by the following relationship (1), and the surface temperature of the belt (14a) has been set so as to satisfy the requirement shown by the following relationship. Tg-30°C
摘要(中):
一种由热塑性树脂制成的光学薄膜的制造方法。 通过该方法,可以获得几乎不具有取向的高度透明的膜。 由热塑性树脂制造的光学膜的制造方法包括:将熔融状态的热塑性树脂从T型模头喷出并形成膜的成型工序; 以及冷却步骤,其中形成为膜的熔融树脂被压在冷却辊(16)和包括设置在带(14a)内部的带(14a)和橡胶辊(14b)的接触辊(14)之间,以及 由此冷却并固化。 在冷却步骤中,冷却辊16的表面温度被设定为满足以下关系(1)所示的要求,并且带(14a)的表面温度被设定为满足 要求由以下关系表示。 Tg-30℃
