<P>PROBLEM TO BE SOLVED: To provide an optical film which suppresses curling caused by annealing for improving antistatic properties, refuse etc., adhesion prevention, and dimensional stability and a thermal history obtained during a working process, is excellent in working properties and adhesion to a hard coat layer, has high durability against ultraviolet rays, and is useful. <P>SOLUTION: The optical laminated polyester film includes coating layers on both sides of a polyester film containing an ultraviolet absorber, and contains an antistatic agent in at least one of the coating layers, wherein the haze of the film is 2.0% or below, the thermal shrinkage factors in the longitudinal direction and the transverse direction of the film after being treated at 150°C for 30 min are 1.5-0.5%, and the difference between the thermal shrinkage factors in the longitudinal direction and transverse direction is 0.5% or below. <P>COPYRIGHT: (C)2009,JPO&INPIT |
