LAMINATED FILM FOR OPTICAL USE, LAMINATED FILM FOR PREVENTING REFLECTION, LAMINATED FILM FOR TOUCH PANEL AND LAMINATED FILM FOR DISPLAYING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a laminated polyester film for an optical use, excellent in transparency, making fine scratches on a substrate film formed in a film-forming process as inconspicuous, without having a cloudy feeling of the laminated film and extremely excellent in easy adhering property and moisture and heat resistant adhering property, and a laminated film for a displaying member by using the same.;SOLUTION: This laminated film for the optical use is provided by installing a coated layer on at least one side surface of a polyester film. The coated layer consists of 2 kinds of resins having different refractive indices, wherein, a high refractive index component layer L1 is in the polyester film side, a low refractive index layer L2 is in the reverse side, and at a boundary of the layers L1 and L2, a mixed phase region of each of the layers is present by 5-100 nm thickness. Total light transmittance is ≥90 %, and haze is ≤1.5 %. The laminated film for preventing reflection is provided by installing a hard coated layer on the coated layer of the laminated film for the optical use.;COPYRIGHT: (C)2004,JPO
