Title:
ADHESIVE COMPOSITION AND ADHESIVE SHEET USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/124686
Kind Code:
A1
Abstract:
The present invention provides an adhesive composition comprising: a urethane oligomer having a radical polymerizable functional group on at least one end thereof; a dilution monomer; and a photo-initiator, wherein: the storage modulus (G') of the adhesive layer at -20℃ and 1Hz after curing is controlled to a particular range; the room-temperature adhesive strength of the adhesive layer to a glass substrate after curing is 5 N/25㎜ or more; and the adhesive strength of the adhesive layer to a glass substrate after heat treatment at 60℃ for 30 seconds is decreased compared with the room-temperature adhesive strength. The adhesive composition according to the present invention has excellent foldability while exhibiting high adhesive strength and superb reworkability.
