Summary: | To provide an adhesive layer which has excellent anti-reflection properties when bonded to an adherend and is capable of suppressing unevenness in the brightness of transmitted light.SOLUTION: A laminated sheet 1 is provided with at least an adhesive layer 21. The adhesive layer 21 has a haze value of 61% or more and a total light transmittance of 69% or less. The laminated sheet 1 may be provided with a layer 42 having anti-glare and/or anti-reflective properties on one surface. The thickness of the laminated sheet 1 is preferably 500 μm or less.SELECTED DRAWING: Figure 1
【課題】被着体に貼り合わせた際の反射防止性に優れ、透過する光の輝度ムラを抑制することが可能な粘着剤層を提供する。【解決手段】積層シート1は粘着剤層21を少なくとも備える。粘着剤層21は、ヘイズ値が61%以上であり、且つ全光線透過率が69%以下である。積層シート1は、一方の表面にアンチグレア性および/または反射防止性を有する層42を備えていてもよい。積層シート1は厚さが500μm以下であることが好ましい。【選択図】図1 |
