摘要： The present invention provides a process for producing a thermoplastic resin sheet with controlled warpage, the process including extruding a thermoplastic resin sheet, while giving mechanically controlled warpage to the sheet at a position where a temperature of the sheet extruded becomes around a grass transition temperature (Tg) of a thermoplastic resin constituting the sheet. In this production process, the sheet is preferably allowed to pass through a pair of warpage-controlling upper and lower rolls at the position, and the mechanically controlled warpage is preferably given to the sheet by selecting shapes of the warpage-controlling rolls and/or by disposing the warpage-controlling rolls on an upper side or a lower side of a height where a flat sheet is obtained. According to this production process, a thermoplastic resin sheet with controlled warpage can be produced simply and easily with high efficiency.

摘要： 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.
