IMPROVEMENTS IN SECURITY DOCUMENTS

摘要

The present invention is directed towards a security document (10) comprising a protective layer (14) overlying a fibrous substrate layer (11) and an elongate security element (16) partially embedded in the fibrous substrate layer (11). The protective layer (14) is at least partially transparent such that the fibrous substrate layer (11) is at least partially visible through the protective layer (14). At least one region (18) of the security element (16) is exposed at a surface (12) of the fibrous substrate layer (11) and is adhered to the protective layer (14). At least one region (17) of the security element (16) is embedded within the fibrous substrate layer (11). The at least one exposed region (18) is substantially indistinguishable to the naked eye when viewed in reflected light incident upon the protective layer (14) and the at least one exposed region (18).
