Title
(EN) OPTICAL FILM
(FR) FILM OPTIQUE
Abstract
(EN)
TAC and TPP were dissolved to a mixture solvent whose main solvent is dichloromethane, such that a dope is prepared. A polymer film (19) is obtained from the dope by a solution casting method. A coating solution containing optical functional materials is prepared. The coating solution is applied to the polymer film (19) to form an optical functional layer (120). Thus an optical film (23) is obtained. The solvent of the coating solution penetrates through a coating surface (19a) into the polymer film (19). Thus the TAC swells or dissolves, such that a mixture layer (121) is continuously formed in the polymer film and the optical functional layer (120). An Averaged thickness L3 ( µm) of the mixture layer (121) is in the range of 0.1 µ m to 10µ m, such that the optical functions appear almost uniformly.

La présente invention concerne un film optique faisant l’objet d’une dissolution de TAC et de TPP dans un mélange de solvant dont le solvant principal est le dichlorométhane, de sorte à préparer un additif. Un film polymère (19) est obtenu à partir de l’additif au moyen d’un procédé de coulée de solution. Une solution de revêtement contenant des matériaux à fonctions optiques est préparée. La solution de revêtement est appliquée au film polymère (19) pour former une couche à fonctions optiques (120). Un film optique (23) est ainsi obtenu. Le solvant de la solution de revêtement pénètre à travers une surface de revêtement (19a) dans le film polymère (19). Le TAC gonfle ou se dissout alors, de sorte qu’une couche de mélange (121) se forme en continu dans le film polymère et la couche à fonctions optiques (120). Une épaisseur moyenne L3 ( µm) de la couche de mélange (121) est comprise entre 0,1 µm et 10 µm, ce qui permet d’obtenir des fonctions optiques quasi uniformes.
