ADHESIVE LAYER FOR OPTICAL FILM, METHOD FOR PRODUCING SAME, OPTICAL FILM WITH ADHESIVE LAYER, AND IMAGE DISPLAY DEVICE |
摘要 |
<p>The pressure-sensitive adhesive layer for an optical film of the invention is formed by a process comprising applying a water-dispersible pressure-sensitive adhesive containing emulsion particles comprising polymer particles emulsified with a surfactant and then drying the applied water-dispersible pressure-sensitive adhesive, and is in such a state that the polymer particles have a number average particle size (a) of 10 nm to 100 nm and that the ratio (a/b) of the number average particle size (a) to the average distance (b) between adjacent polymer particles is from 80/20 to 99.9/0.1, when the pressure-sensitive adhesive layer being observed with a transmission electron microscope. The pressure-sensitive adhesive layer makes it possible to reduce depolarization even when it is used on a high-contrast polarizing plate or any other component having a high degree of polarization.</p> |
