FIELD: information technology.
SUBSTANCE: protective element has a structure with optically variable properties, formed by a die-stamped structure and a coating which are combined with each other such that at least part of the coating is completely visible when looking at the protective element at a right angle of view, but not visible when viewed at an acute angle of view. The die-stamped structure is formed by nonlinear die-stamped elements which are combined with the coating such that when the direction of viewing the protective element is changed, different information becomes visible.
EFFECT: improvement of protective element with optically variable properties which is suitable for visual checking, longevity of the protective element.
