PRESSURE-SENSITIVE ADHESIVE SHEET WITH PEELING DISPLAY FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet with peeling detecting functions more surely and clearly exhibiting a peeling display even when the adhesive sheet is peeled at a low speed or peeled from an adherend having low adhesion. SOLUTION: The pressure-sensitive adhesive sheet has peeling display functions to visibly display the peeling display to be an evidence for peeling from an article when peeled from the article by observation from the surface side. The pressure-sensitive adhesive sheet has a structure in which a pressure-sensitive adhesive layer 2 is laminated onto the whole surface or a part of a substrate layer support 4 so as to cover the substrate layer 1 having the substrate layer support 4 and a peelable layer 5 formed in a part of one surface of the substrate layer support 4 and the peelable layer 5. The substrate layer support 4 is a film made of transparent or translucent polyethylene terephthalate and the peelable layer 5 contains an acrylic resin. Furthermore, the pressure-sensitive adhesive sheet with the peeling display functions in which the peeling display appears between the substrate layer support 4 and the peelable layer 5 is used as the peeling display.
