Abstract
The present invention concerns a strip for safeguarding a document, comprising a support on which there is formed in the longitudinal direction of the strip an alternation of generally metallised regions and generally transparent regions, said alternation being capable of establishing a contrast on a scale identified as global at the level of the document to be safeguarded in such a way as to constitute protection against reproduction of the documents with which the strip will be associated, characterised in that the strip also comprises optically active elements in association with the generally metallised regions and/or the generally transparent regions of the strip to produce an optical effect on a scale identified as detail at the level of the document to be safeguarded, said optical effect making it possible to constitute a recognisable sign for identifying said document. The present invention finally concerns a security document incorporating a strip as set forth hereinbefore.
