ABSTRACT:
On a printing substrate an inking interlaced multilayer is coated which incorporates a latent configuration to be rendered visible as an actual irreversible image at any later moment by its transposal onto a new support, the obtained product being applicable as a protection against counterfeiting on commercial articles, packings, for publishing, advertising, certification purposes and so on. FIG. 6 shows an active label-seal in which the latent disc-shaped configuration is transposed from the printing substrate on the packing 12 provided as support, when the label-seal 13 is separated in stripping from said packing 12 off the closure line 14. FIG. 7 shows a counterfeiting-protective device in which the inking interlaced multilayer on substrate 18 representing a trademark and a countersign incorporates a latent configuration performing as an active seal 28 as X, capable of displaying the corresponding actual image on a new support when the printing substrate, after being adhesively fastened to the new support, is then detached from the same.
