<p><P>PROBLEM TO BE SOLVED: To provide a polyether film which has surface characteristics of preventing the generation of interference fringes even when used in contact with a plate glass, and a transparent member of a transparent resin film, sheet and molded product and is excellent in discoloration preventing properties against ultraviolet. <P>SOLUTION: The polyester film for optical use comprises protrusions having five or more-dimensional interference fringes observed by a double-beam interference method, and the density of the protrusions (piece/mm<SP>2</SP>) is at least 0.7 on one side of the surfaces. The polyester film for optical use comprises an ultraviolet absorber in the film and light transmission at 360 nm wavelength is≤10%. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
