ADHESIVE OPTICAL FILM AND IMAGE DISPLAY DEVICE |
摘要 |
<p>A pressure-sensitive adhesive optical film of the present invention comprises: an optical film; and a pressure-sensitive adhesive layer placed on at least one side of the optical film, wherein the pressure-sensitive adhesive layer has an equilibrium moisture content ratio (a) of 0.5% by weight or less, the pressure-sensitive adhesive layer shows a displacement amount (b) of 600 µm or less in one hour at 23°C, when a tensile shearing stress of 500 gf is applied to an adhesion area of 10 mm x 10 mm having a thickness of 25 µm, and the equilibrium moisture content ratio (a) and the displacement amount (b) satisfy the relation: b<1036.4 x e -5.124a . The pressure-sensitive adhesive optical film can have high durability in high-temperature environments and be prevented from foaming in such environments, even when the optical film on which the pressure-sensitive adhesive layer is placed is made of a material with low moisture permeability.</p> |
