摘要：PURPOSE:To obtain the polyester film prominent in forming property by a method wherein the refractive index (nalpha)of the film in the direction of thickness thereof and the average refractive index (n') of the same are specified to specific values. CONSTITUTION:The average refractive index (n') is preferable to be 1.600 or more and 1.607 or less. In ca (n') is lower than 1.600, size change due to contraction during using the film is caud and it is not preferable. On the other hand, in ca (n') exceeds 1.607, the forming property of the film is deterio rated and it is not preferable. The preferable value is 1.605 or less. The refrac tive index (nalpha) of the film in the direction of thickness thereof is necessary to be 1.492 or more. In ca (nalpha) is up to 1.492, the surface orientation of the film becomes too high and the forming property of the film is deteriorated, therefore, it is not preferable. Paradoxically speaking, the forming property of film is improved remarkably in the film who (n(-)) is 1.492 or more.
