发明名称 Security element
摘要 The security element consists of a translucent plastic base layer (7), an opaque layer (3) and magnetic layer (5) beneath the opaque layer. The opaque layer has cut-outs (4) detectable during transmission of light. The cut-outs are shaped as characters, patterns. The magnetic layer is in the form of separate magnetic regions (5) forming a code. The cut-outs are arranged in the intermediate regions of the code which are free of the magnetic layer.
