Title (EN) OPTICAL FILM, RELEASE METHOD, AND METHOD FOR MANUFACTURING OPTICAL DISPLAY PANEL
(FR) FILM OPTIQUE, PROCÉDÉ DE PELAGE ET PROCÉDÉ DE FABRICATION DE PANNEAU D'AFFICHAGE OPTIQUE

Abstract:
(EN) The present invention is a sheet-form film laminate in which a first release film having a first base-material film and a second release film having a functional film and a second base-material film are laminated, wherein the first release film is detached prior to the second release film, the functional film has a thickness of 110 μm or less, and a first bending resistance (mm) in a bending test of the first release film is greater than a second bending resistance (mm) in a bending test of the second release film. In this laminate, the first release film (the release film on the side that is released first) can be easily released even when a thin functional film is used.
(FR) La présente invention concerne un stratifié de film en forme de feuille dans lequel un premier film anti-adhésif ayant un premier film de matériau de base et un second film anti-adhésif ayant un film fonctionnel et un second film de matériau de base sont stratifiés, le premier film anti-adhésif étant détaché avant le second film anti-adhésif, le film fonctionnel a une épaisseur de 110 µm ou moins et une première résistance à la flexion (mm) dans un test de flexion du premier film anti-adhésif est supérieure à une seconde résistance à la flexion (mm) dans un test de flexion du second film anti-adhésif. Dans le stratifié selon l'invention, le premier film anti-adhésif (le film anti-adhésif sur le côté qui est pelé en premier) peut être facilement pelé même lorsqu'un film fonctionnel mince est utilisé.
(JA) 本発明は、第1基材フィルムを有する第1剥離フィルム、機能フィルムおよび第2基材フィルムを有する第2剥離フィルムがこの順に積層されている枚葉状のフィルム積層体であって、前記第1剥離フィルムは、前記第2剥離フィルムよりも先に剥がすものであり、前記機能フィルムは、厚みが110μm以下であり、かつ、第1剥離フィルムの剛軟性試験における第1剛軟度(mm)が、第2剥離フィルムの剛軟性試験における第2剛軟度(mm)よりも大きい。本発明の積層体は、薄型の機能フィルムを用いた場合であっても、第1剥離フィルム(初めに剥離を行う側の剥離フィルム)を容易に剥離することができる。
