Document Type and Number:
WIPO Patent Application WO/2023/190078
Kind Code:
A1
Abstract:
One purpose of the present invention is to provide an adhesive sheet for optical applications, the adhesive sheet being capable of suppressing the generation of static electricity when the adhesive sheet is separated from an image display panel for rework of the image display panel. Another purpose of the present invention is to provide an adhesive sheet for optical applications, the adhesive sheet having an adhesive layer that exhibits excellent level difference absorbing properties. An adhesive sheet 10A for optical applications according to the present invention has a multilayer structure which comprises a base material 1 that has a first surface 1a and a second surface 1b and an adhesive layer 2 that is superposed on the first surface 1a of the base material 1. The adhesive layer 2 contains an antistatic agent which is in a liquid state. The adhesive layer 2 has a surface resistance of less than 10 10 Ω. The adhesive layer 2 has a hardness H (kPa) of less than 60 kPa as determined by a nanoindentation method.
