Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive sheet leaving a mark on the sheet by opening the seal of the adhesive sheet without leaving adhesive on the adherend. SOLUTION: The peel-detecting adhesive sheet is at least composed of a substrate layer, a releasing agent layer, an intermediate layer and an adhesive layer laminated in the order. A visually recognizable deformation is generated by applying a peeling force between the releasing agent layer and the intermediate layer and the applied adhesive sheet is peelable without leaving the adhesive on the adherend. The figure shows the state obtained by peeling the adhesive sheet applied to an adherend. The reference number 8 is the part of the intermediate layer having interlayer peeling, 9 is the part having different light reflection state and 10 is the part of the intermediate layer contacting with the substrate layer.
