Title:
ADHESIVE COMPOSITION FOR COATING-TYPE POLARIZATION ELEMENT, ADHESIVE SHEET FOR COATING-TYPE POLARIZATION ELEMENT, ADHESIVE SHEET FOR IMAGE DISPLAY DEVICE CONSTITUTING MEMBER, ADHESIVE SHEET WITH MOLD RELEASE FILM, ADHESIVE SHEET WITH IMAGE DISPLAY DEVICE CONSTITUTING MEMBER, LAMINATE SHEET, COATING-TYPE POLARIZATION ELEMENT WITH ADHESIVE LAYER, ADHESIVE SHEET WITH POLARIZATION ELEMENT, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/113544
Kind Code:
A1
Abstract:
This adhesive composition includes a (meta)-acrylic polymer (A), a ultraviolet ray absorber (B), and a radical polymerization initiator (C). When used in combination with a coating-type polarization element, an adhesive composition for a coating-type polarization element having a transmissivity of 50% or less at a wavelength of 400 nm in an adhesive layer formed of the adhesive composition is capable of preventing the coating-type polarization element from reducing polarization performance with time due to exposure.
