SECURITY ELEMENT COMPRISING PARTIAL MAGNETIC LAYER Russian patent published in 2008 - IPC B42D15/10 B32B37/00 

FIELD: textiles; paper.

SUBSTANCE: invention relates to a security element, particularly a security thread for value documents such a banknotes, credit cards, identification papers, or tickets, comprising at least one partial magnetic layer for storing a coded piece of information. Also disclosed is a method for producing said security element. This is the method for producing a security element including a second film member with a partial magnetic coating, whereby an adhesive layer made of a radiation crosslinking adhesive is applied to a first film member. Said adhesive layer is applied to the base film from the radiation crosslinking adhesive in a structured pattern-like shape and/or is irradiated in a pattern-like manner such that the adhesive layer hardens so as to form a pattern-like structure. A transfer film encompassing a support film and a magnetic layer that faces the adhesive layer is applied to the adhesive layer. Then the support film is removed from the second film member comprising the first film member, the adhesive layer, and the magnetic layer having the form of said partial magnetic coating. The magnetic layer remains thereby on the first film member in a first structured pattern-like zone while said magnetic layer remains on the support film in a second structured pattern-like zone and is removed from the first film member along with the support film.

EFFECT: present invention provides a process for producing an enhanced security element and makes it possible to avoid undesirable grain formation and deformations.
