Document Type and Number:
WIPO Patent Application WO/2022/210276
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a radiation-curable adhesive sheet with which the progress of curing during storage can be suppressed, with which excellent thickness unevenness absorbability and stress relaxation properties can be maintained for a long time, and which has excellent storage stability. A radiation-curable adhesive sheet 1 according to the present invention has an adhesive layer 10 that is cured by irradiation with radiation. The adhesive layer 10 includes a photopolymerization initiator 11a and a crosslinking agent 11b, and the curing by irradiation with radiation is performed by a reaction with the photopolymerization initiator 11a and the crosslinking agent 11b. The radiation-curable adhesive sheet 1 is characterized in that the adhesive layer 10 further includes a hindered amine-based light stabilizer 11c.
