发明名称 SECURITY ELEMENT HAVING A MICROSTRUCTURE
摘要 The invention relates to a security element for security papers, value documents and the like with at least one microstructure which has a visual appearance that is viewing angle-dependent in transmission, whereby the at least one microstructure is formed from an arrangement of a multiplicity of structure elements with a characteristic structure spacing of 1 μm or more. According to the invention it is provided that the security element contains at least one motif image which, through the viewing angle-dependent visual appearance of the microstructure, is visible in transmission from certain viewing angles, and invisible in transmission from other viewing angles, and that the microstructure and the motif image together have a thickness of 50 μm or less.
