<p>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive tape or label for sealing which, when peeled from an adherend, does not leave behind a pressure-sensitive adhesive or a substrate containing a colored layer (a print layer) at all on the adherend and which, when restuck, causes a marking shape with a color different from the original color to appear, enabling unsealing to be discriminated. SOLUTION: This pressure-sensitive adhesive tape or label comprises a substrate 6 and a pressure-sensitive adhesive 5 peelable without leaving behind the adhesive or a part of the substrate. The substrate is a laminate of at least two colored clear plastic films different in hue or tone, the laminate being made so that the interlayer adhesive power of the laminate is smaller than the power required for peeling the substrate from an adherend 11; hence, in peeling from the adherend, a partial interlayer peeling occurs in the laminate, causing an air layer 10 to appear at the interlayer peeling site, thus causing a marking shape 12 having a visibly different hue or tone to appear when the tape or label is restuck.</p> |
