Document Type and Number:
WIPO Patent Application WO/2019/026762
Kind Code:
A1
Abstract:
The present invention relates to a photocurable adhesive sheet containing an ultraviolet absorbing agent, and provides a novel adhesive sheet having ultraviolet-resistant foaming properties without compromising photocuring performance. Provided is an adhesive sheet characterized by having an adhesive layer formed from an adhesive composition containing an ultraviolet absorbing agent and a photoinitiator, the ultraviolet absorbing agent having an extinction coefficient of 1×103mL/(g∙cm) or greater at a wavelength of 340 nm and an extinction coefficient of less than 1×103mL/(g∙cm) at a wavelength of 380 nm, and the adhesive composition containing the ultraviolet absorbing agent at a ratio of 0.1-1.6% by mass with respect to the entire mass of the adhesive composition.
