HOLOGRAPHIC ELEMENT FOR SECURITY LABELS AND TAPES Russian patent published in 2021 - IPC G09F3/02 

FIELD: security labels and tapes.

SUBSTANCE: invention relates to the field of security labels, as well as protective sealing and packaging tapes with indicators of unauthorized access (interference). The problem is solved by introducing holographic elements containing transparent multilayer thin-film color-variable structures into the structure of security labels and tapes. The introduction of such structures into holographic elements increases the clarity, contrast and brightness of the monitored holographic images and the changes occurring in them when attempting to unauthorized access to the objects they protect. The economic efficiency of the proposed invention is determined by an increase in the number of detected during control, including operational, operations to identify counterfeit and falsified products and registration and cases of unauthorized access (interference) to protected objects.

EFFECT: problem solved in the proposed technical solution is to increase the reliability of the results of authenticity control and registration of the facts of unauthorized access to products (objects) protected by such labels and tapes.
