Summary: | To provide a base material laminate body in which an end piece of an optical laminate body manufactured in the step of manufacturing a polarizer can be easily removed.SOLUTION: A base material laminate body A includes a base material layer 2 and a surface processing layer 3 directly laminated on the surface of the base material layer 2. The base material laminate body A includes a pair of end parts AE facing each other in a direction substantially parallel to the surface of the base material layer 2 and a center part AC between the pair of end parts AE. The strength of separation of the base material layer 2 from the surface processing layer 3 in at least one of the end parts AE of the base material laminate body A is denoted by Ie. The strength of separation of the base material layer 2 from the surface processing layer 3 in the center part AC of the base material laminate body A is denoted by Ic. Ie is larger than Ic.SELECTED DRAWING: Figure 1
【課題】偏光板の製造過程で作製される光学積層体の端部片を容易に除去することができる基材積層体の提供。【解決手段】基材積層体Aは、基材層2と、基材層2の表面に直接積層された表面処理層3と、を備える。基材積層体Aは、基材層2の表面に略平行な方向において対向する一対の端部AEと、一対の端部AEの間に位置する中央部ACと、を含む。基材積層体Aの少なくとも一方の端部AEにおける表面処理層3に対する基材層2の剥離強度は、Ieと表される。基材積層体Aの中央部ACにおける表面処理層3に対する基材層2の剥離強度は、Icと表される。Ieは、Icよりも高い。【選択図】図1 |
