发明名称 SECURITY ELEMENT HAVING A PLURALITY OF OPTICALLY VARIABLE STRUCTURES
摘要 The invention relates to a security element comprising an optically variable structure having an embossed structure. Upon tilting of the security element about an axis and thus alternate observation from a first and second observation angle range, a tilting effect arises which shows different colours or brightnesses from the two different viewing angles or at different angles of light incidence. According to the invention, the optically variable structure has at least one second embossed structure which is arranged within the first embossed structure and produces a second tilting effect in addition to the first tilting effect. In this case, the second tilting effect occurs either within the first or second observation angle range or upon the transition from the first to the second or from the second to the first observation angle range.
