FIELD: protective devices.
SUBSTANCE: protective device comprises a protective component containing at least first and second regions, which reproduce respectively first and second optical effects, each of which has at least two characteristic dimensions in various configurations for monitoring component. More precisely, said device comprises an image which is at least partially relief, produced by deformation of said component and substrate on which component is fixed, said image containing at least first and second graphic elements passing at least partially in two areas, and at least said first and second graphic image elements respectively open in first and second regions due to occurrence of at least one of two aspects of first and second optical effects, respectively. Said image is configured so that first and second elements are hidden in case of visibility of other of two aspects of respectively first and second optical effects, where in same observation configuration said first graphical element is open, and second graphical element is hidden.
EFFECT: invention improves protection from forgery.
