发明名称 Security element with identification marks
摘要 The element (12) has an optically non-variable color layer (32) covered in a covering region of an optically variable effect layer (40) and provided with a partial region (34) with fixed color impression and another partial region (36) with a different color impression. Individualized identification (14) is produced at the covering region and the color layer to display the color impressions in the former partial region. The partial regions are aligned with each other such that variable color impression of the effect layer below a preset viewing angle corresponds to the fixed color impression. The individualized identification is provided by infrared laser such as carbon dioxide laser, neodymium-doped yttrium aluminum garnet-laser or neodymium doped yttrium orthovanadat-laser. An independent claim is also included for a method for manufacturing a safety element for securing valuable articles.
