Title:
活性エネルギー線硬化型粘着剤組成物及び粘着シート、並びに、その利用
Document Type and Number:
Japanese Patent JP7327394
Kind Code:
B2
Abstract:
[Problem] To provide: an active energy ray-curable adhesive composition and adhesive sheet, with which a thin film substrate and an inorganic substrate can be temporarily bonded with adhesiveness when joining the same, and in which peeling and foaming do not occur even in the event of exposure to high temperature, and peeling can be easily achieved at any interface of a thin film substrate or an inorganic substrate by means of irradiation with active energy rays. [Solution] The present invention provides an active energy ray-curable adhesive composition containing components (A) and (B) below, wherein a coating film obtained from the composition has a lower 180° peel strength after being irradiated with active energy rays than before being irradiated with active energy rays. Component (A): A copolymer having a photosensitive group and having a glass transition temperature of -10°C to 40°C. Component (B): A degradation inhibitor which contains an antioxidant as an essential component, the antioxidant essentially containing a phenol-based antioxidant, and further containing a phosphorous-based antioxidant and/or a sulfur-based antioxidant.
