Document Type and Number:
WIPO Patent Application WO/2024/019156
Kind Code:
A1
Abstract:
The present invention provides an adhesive sheet which can be manufactured with a low environmental load by reducing the disposal volume of a release liner required for manufacturing the adhesive sheet. An adhesive sheet 1 according to the present invention is formed from a photocurable adhesive composition containing: a monomer group including a (meth)acrylic monomer and/or a partially polymerized product of the monomer group; and a photopolymerization initiator. The thickness of the adhesive sheet 1 is 5-100 μm. The adhesive composition further contains an antioxidant. The antioxidant contains at least one selected from the group consisting of a hindered phenol-based compound, a hindered amine-based compound, and a phosphorus-based compound, and has a molecular weight of at most 1,000.
