FIELD: production of a paper protected against a counterfeit.

SUBSTANCE: the invention is pertaining to manufacture of a paper protected against a counterfeit and used for manufacture of the important documents, such as banknotes, certificates and other analogous important documents, and which has at least one multilayer protective element capable to form at least one visually checkable optical effect. This protective element is at least partially is placed on the surface of the paper protected against a counterfeit and supplied at least with one integrated circuit. At that the protective element has at least one layer containing pigments with optically variable properties, first of all - interferential or liquid-crystal pigments. So the invention ensures production of a simple and inexpensive in manufacture important document, which allows to form an suitable to the visual control optical effect and simultaneously make it possible to conduct a machine check.

EFFECT: the ensures production of a simple and inexpensive in manufacture important document, formation of an suitable to the visual control optical effect and simultaneously permits a machine check.
