Document Type and Number:
WIPO Patent Application WO/2024/019157
Kind Code:
A1
Abstract:
The present invention provides an adhesive sheet which is suitable for adjusting the anchoring power between itself and an optical film to a large value. An adhesive sheet 1 according to the present invention is formed of a photocurable composition which contains a monomer group and/or a partial polymerization product of the monomer group. With respect to this adhesive sheet 1, the added amount of a hydroxy group-containing monomer is less than 5 parts by weight per 100 parts by weight of the monomer group. The photocurable composition additionally contains an isocyanate-based crosslinking agent; and the added amount of the isocyanate-based crosslinking agent is 0.02 part by weight or more relative to a total of 100 parts by weight of the monomer group and the partial polymerization product.
