A method of manufacturing a security article (10) is provided, comprising applying an first adhesive layer to a substrate (11), the first adhesive layer comprising an additive which is responsive to at least a selected wavelength of laser radiation (12); and applying a laminate over the first adhesive layer, the laminate comprising a second adhesive layer which adheres to the first adhesive layer. Prior to applying the laminate over the first adhesive layer, data is printed onto the first and/or second adhesive layer, such that on applying the laminate over the first adhesive layer, the printed data is incorporated between the first and second adhesive layers. Also provided is a security article comprising a substrate having upper and lower surfaces; a first adhesive layer applied to the upper surface of the substrate, the first adhesive layer comprising an additive which is responsive to at least a selected wavelength of laser radiation; a print layer; and a laminate comprising a second adhesive layer bonded to the first adhesive layer. The print layer is incorporated between the first and second adhesive layers. |
