PROTECTIVE ELEMENT WITH STRUCTURE HAVING OPTICALLY ALTERNATING PROPERTIES Russian patent published in 2011 - IPC B42D15/00 B41M3/14 

FIELD: printing industry.

SUBSTANCE: invention relates to a protective element, method of its manufacturing, an information carrier with a similar protective element, and also to application of the specified protective element for protection of goods and items against counterfeit. The protective element with the structure having optically variable properties is formed by stamped structure of linear stamped elements and a coating. The stamped structure and the coating are arranged relative to each other so that at least parts of the coating are fully visible, when the protective element is examined at the right angle of vision, but are invisible when it is examined at the acute angle of vision. Mainly the whole coating is formed by non-linear main elements, characterising parametres of which are their contour, dimensions, colour and orientation, and which are combined with the stamped structure so that whenever direction of the protective element examination changes, different information becomes visible.

EFFECT: increased extent of the specified protective element counterfeit protection.
