Title:
METHOD FOR PRODUCING ADHESIVE SHEET AND METHOD FOR PRODUCING OPTICAL FILM INCLUDING ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2024/019158
Kind Code:
A1
Abstract:
Provided is a method for producing an adhesive sheet, the method comprising subjecting a first adhesive sheet, comprising a polymer of a monomer and a remaining monomer, to a surface modification treatment in which an active energy ray is used, to obtain a second adhesive sheet in which the amount of the remaining monomer is reduced compared to the first adhesive sheet. The surface modification treatment is, for example, at least one treatment selected from the group consisting of a corona treatment, a plasma treatment, an excimer UV light treatment, and a flame treatment. This production method is suitable for producing an adhesive sheet in which a reduction in an anchoring force is suppressed while also having a reduced amount of a remaining monomer.
