BASE FILM FOR PROTECTIVE FILM AND PROTECTIVE FILM COVERED POLARIZING PLATE

摘要

The present invention provides a protective-film-use base material film which exhibits small birefringence and also exhibits excellent solvent resistance and excellent heat resistance at the time of heating, and a protective film laminated polarizer which laminates the protective-film-use base material film thereto. A protective-film-use base material film 10 is constituted of a non-oriented three-layered film 3 which is formed by laminating a polyester film 9 to both surfaces of a polycarbonate film 8, wherein a ratio of a film thickness of a polycarbonate film to a film thickness of a polyester film (film thickness of polycarbonate film/film thickness of polyester film) in the three-layered film constitution is set to 0.1 or more and less than 5. A protective film laminated polarizer 7 is formed by laminating the protective-film-use base material film 10 to one or both surfaces of the polarizer 3.
