发明名称 Polarizing Plates Having Polyester Film For Release Film
摘要 <p>Provided in the present invention is a polyester film useful for making the release films, which contains the particles having an average particle size in the range of 0.2 to 1.5 µm and a particle size distribution factor (d25/d75) in the range of 1.0 to 2.0. Preferably, the amount of oligomer on the film surface after having been coated with methyl ethyl ketone, dried and heat treated at 180°C for 10 minutes is 5.0 mg/m 2 or less. The polyester film of the present invention excels in optical properties which are one of the important characteristics of the films to be used for liquid crystal displays or such, and is capable of providing high-degree precision in detection of faults in film inspection. Specifically, the film of the present invention is capable of realizing high-degree precision and easy detection of faults in the inspections of the films by the Cross Nicol method which is one of the vital inspection techniques in the production process of polarizing plates.</p>
