The invention discloses an optical stack, which includes an optical film (200) and an optical adhesive (500) disposed on the optical film. The optical adhesive has a major structured surface facing away from the optical film that includes a plurality of channels formed therein. The channels define a plurality of substantially flat land regions therebetween. The land regions include at least about 50% of a total surface area of the major structured surface. When the optical stack is placed on a support surface with the major structured surface of the optical adhesive contacting the support surface, the optical stack bonds to the support surface and may be removed from, or slidingly repositioned on, the support surface without damage to the optical adhesive or the support surface, and upon application of at least one of heat and pressure, the optical stack substantially permanently bonds to the support surface and the plurality of channels substantially disappear.

    本发明公开了一种光学叠堆,该光学叠堆包括光学膜(200)和设置在该光学膜上的光学粘合剂(500)。该光学粘合剂具有背对该光学膜的主结构化表面,该主结构化表面包括形成于其中的多个通道。这些通道之间限定多个基本上平坦的台面区域。这些台面区域占该主结构化表面的总表面积的至少约50%。当该光学叠堆放置在支撑表面上且该光学粘合剂的该主结构化表面接触该支撑表面时,该光学叠堆粘结到该支撑表面并且能够在不损坏该光学粘合剂或该支撑表面的情况下从该支撑表面移除或以滑动的方式在该支撑表面上重新定位,并且在施加热和压力中的至少一者时,该光学叠堆基本上永久性地粘结到该支撑表面,并且该多个通道基本上消失。
