FIELD: information carrier with a structure possessing optically variable properties, embossing die designed for manufacture of the carrier, method for manufacture of the carrier and use of the die for its manufacture.
SUBSTANCE: the information carrier (1) has a structure (2) possessing optically variable properties, consisting of an embossed structure and a coating contrasting with the surface of the information carrier. Such an embossed structure and a coating are combined in such a way that at least some sections of this coating are completely seen at a right angle of vision, and at an acute angle of vision they become invisible as a result of which a Kipp-effect is produced at an alternative consideration at right and acute angles of vision. Such a coating is made uniform, and the embossed structure is subdivided into separate sections with various embossed substructures provided on them.
EFFECT: enhanced degree of carrier protection against falsification by reproduction, enhanced convenience of visual check.
