WIPO Patent Application WO/2020/013212
Kind Code:
A1
Abstract:
The present invention relates to a peel-off detection label which is a laminate having, in the following order: a support; a pattern layer formed on a portion of the surface of the support; and an adhesive laminate having at least a low modulus layer (X), a high modulus layer (Y), and an adhesive layer (Z), wherein the low modulus layer (X) has the surface adjacent to the support and the pattern layer and the surface adjacent to the high modulus layer (Y), and requirement (1) is satisfied. Requirement (1): as analyzed by a finite element method using Abaqus, the maximum vertical tensile stress applied to an element located closest to the support of the low modulus layer (X) when the adhesive layer (Z) of the peel-off detection label is attached to an adherend, and then the peel-off detection label is peeled off from the adherend is 0.19 MPa or more.
