Abstract
Methods and adhesive labels useful in marking products or documents by applying these to substrates. A mark such as a barcode, photograph or characters are formed directly on the substrate and the adhesive label is applied over it. The adhesive label includes a concealing film layer which is transparent to a first wavelength outside the visible region, a diffractive optical mark with a transparent reflective layer and an adhesive layer. The first wavelength may be infrared allowing the underlying mark to be read by an IR laser. The adhesive labels are formed as to allow them to be continuously separated from a temporary detachment layer, thereby exposing the adhesive layer, and affixed to the document.
