Title:
ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2020/110489
Kind Code:
A1
Abstract:
Provided is an adhesive sheet containing an adhesive layer. The adhesive layer contains: a polymer A constituted by a polymerized product of a monomer feedstock A; and a polymer B constituted by a polymerized product of a monomer feedstock B containing a monomer, having a polyorganosiloxane skeleton, and a (meth)acrylic monomer. The polymer B has an Mw of 7 × 104 or higher. The relationship between the adhesive strength N50 of the adhesive sheet as measured at 23°C after being applied to a stainless steel plate and kept at 50°C for 30 minutes and the adhesive strength N80 of the sheet as measured at 23°C after being applied to a stainless steel plate and kept at 80°C for 5 minutes satisfy the formula (N80/N50) ≥ 3.
