FIELD: printing industry.
SUBSTANCE: invention relates to protective label or adhesive tape with manipulation indication, that has optically active protective element and optical element. Protective label or adhesive tape with manipulation indication has flexible carrying substrate (1) based on flexible synthetic film. The following layers are applied to the carrying substrate: textured layer (2) of varnish, semitransparent metal layer, or respectively layer with high refraction index (3), partial separating layer (4) of varnish in form of letters, symbols, lines, guilloche, numbers or dashes, one or several layers (5) of varnish with optical properties, self-adhesive coating (6). At sections not coated with separating layer (4) of varnish adhesion of all layers with each other and adhesion of layer (6) and protected object is larger then adhesion of layer (5) with layer (6), or adhesion of all layers with each other is larger then adhesion of layer (6) with protected object (9). At that at sections coated by the separating layer (4) of varnish the adhesion of all layers with each other, and adhesion of layer (6) and protected object (9) is larger then adhesion of layer (3) with layer (4) or adhesion of layer (4) with layer (5).
EFFECT: increased protection.
