Abstract

La présente invention concerne un film stratifié muni d'un film de substrat, qui comprend une résine thermoplastique et une couche de résine d'alcool polyvinylique formée au moyen du revêtement sur au moins une surface du film de substrat, lequel présente une élasticité à la traction à 80 °C d'au moins 140 MPa ; un film stratifié de polarisation qui utilise le film stratifié ; et un procédé de production d'une plaque de polarisation. De préférence, sur le film de substrat, la couche de surface d'au moins la surface sur laquelle a été formée le film de résine d'alcool polyvinylique est conçue à partir d'une résine thermoplastique cristalline, qui présente une cristallinité d'au moins 58 %.
