Abstract

L'invention concerne un film d'alcool de polyvinyle utile pour produire un film polarisant n'ayant que quelques plis. Le film d'alcool de polyvinyle est un film optique qui utilise une résine d'alcool de polyvinyle comme matériau brut principal. L'inclinaison de l'axe optique dans le sens de la largeur du film est de 45 à 135 ˚ par rapport au sens de la longueur du film sur toute la largeur du film. Le film d'alcool de polyvinyle peut avoir un rapport d'étirement limite supérieur à 6,0 mais inférieur à 8,0, et un rapport d'allongement au gonflement d'environ 100 à 124 %.
