Abstract
A release agent is first applied to a target article and on top of the release agent is applied an ultraviolet radiation fluorescent material to enable fraud detection. To prevent fraud, a security label may also be used comprising a label substrate, a release layer, a layer of ultraviolet radiation fluorescent material, and an adhesive layer for adhering to a target article. When the substrate is peeled off, part of the ultraviolet sensitive material will be peeled off also to enable detection.
