Document Type and Number:
Japanese Patent JP6803673
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an extensible pressure sensitive adhesive sheet capable of exerting a sufficient adhesive function in use, while having excellent tensile removal properties at removal.SOLUTION: An extensible pressure sensitive adhesive sheet 1 includes adhesive layers 21, 22. The pressure sensitive adhesive sheet 1 has a total thickness of 150 μm or less, an initial adhesive force A of 2 N/20 mm or more to polycarbonate, and tensile peeling stress B of 16 N/20 mm or less to polycarbonate. The pressure sensitive adhesive sheet 1 includes a film-like substrate 10 supporting the adhesive layers 21, 22. The film-like substrate has 300% extension stress Sof 5 MPa or less.SELECTED DRAWING: Figure 1
