BIAXIALLY ORIENTED POLYESTER FILM, ADHESIVE FILM, AND LAMINATED FILM |
摘要 |
A biaxially oriented polyester film for optical use which combines handleability with a hue contrast; an adhesive film; and a laminated film. The biaxially oriented polyester film contains a colorant incorporated therein and has a haze of 5% or lower. In this film, the average light transmittance in the wavelength range of 450 to 650 nm, Tav, is 40 to 80%, and the value obtained by dividing the light transmittance (Ti) at each wavelength, i, within that wavelength range by the Tav is 0.7 to 1.3. The adhesive film and the laminated film are made with the biaxially oriented polyester film.
