PROTECTING MAGNETIC FILAMENT FOR IDENTIFYING VALUABLE ARTICLES, METHOD FOR MAKING IT AND VALUABLE PAPER WITH SUCH FILAMENT Russian patent published in 2007 - IPC B32B15/04 B32B7/02 B42D15/10 B42D107/00 B32B15/09 B32B15/20

Abstract RU 2292267 C9

FIELD: processes of making protecting members such as filaments for protection against counterfeit of valuable papers, possibly determination of authenticity of bank notes and other bank-papers and credit documents.

SUBSTANCE: protecting magnetic filament includes polymeric film base onto which laminate structure of protecting means is formed. Such structure includes first masking layer of metallic material applied on base and successively arranged layer of magnetic material to be detected, additional masking layer of metallic material and outer covering film layer of polymeric material. First masking layer is arranged between surface of polymeric film base and layer of detected magnetic material whose characteristic magnetic parameters are limited by respective values: 0.1 Oe < Hc < 1 Oe; Hc/Hs ˜= 0.95 -0.98 where Hc - coercive force of magnetic material; Hs - saturation field of magnetic material.

EFFECT: enhanced degree of protecting valuable papers.
