Abstract
(EN)
Provided is an optical film laminate wherein pressure-sensitive adhesive layers are not exposed to the outside. In a method for manufacturing said optical film laminate, the widths of a second film (32) and third film (33) which are laminated onto a first film (31) are both made smaller than the width of the first film (31), and the second film (32) and third film (33) are sequentially laminated onto the first film (31) such that neither protrudes past the first film (31) in the width direction. Thus, pressure-sensitive adhesive layers (32A and 33A) in the optical film laminate (30) are not exposed to the outside.
(FR)
L'invention concerne un film optique stratifié renfermant des couches d'adhésif sensible à la pression qui ne sont pas exposées à l'environnement extérieur. Dans un procédé de fabrication dudit film optique stratifié, les largeurs d'un deuxième film (32) et d'un troisième film (33) qui sont laminés sur un premier film (31) sont toutes deux rendues inférieures à la largeur du premier film (31), et le deuxième film (32) et le troisième film (33) sont laminés en séquence sur le premier film (31) de telle sorte que ni l'un ni l'autre ne dépassent du premier film (31) dans la direction de la largeur. Ainsi, les couches d'adhésif sensible à la pression (32A et 33A) dans le film optique stratifié (30) ne sont pas exposées à l'environnement extérieur.

粘着層が外部に露出することがない光学フィルム積層体を提供する。光学フィルム積層体の製造方法において、第1フィルム31上に積層する第2フィルム32及び第3フィルム33の幅を、いずれも第1フィルム31の幅よりも小さくするとともに、第2フィルム32及び第3フィルム33を、いずれも第1フィルム31に対して幅方向にはみ出さないように、第1フィルム31上に順次に積層する。これにより、光学フィルム積層体30の粘着層32A,33Aが外部に露出することがない。
