Zusammenfassung:The present invention relates to the field of the protection of value documents and value commercial goods against counterfeit and illegal reproduction. In particular, the present invention relates to security threads or stripes to be incorporated into or onto security documents. The security threads or stripes comprise i) an optically variable layer (1) imparting a different color impression at different viewing angles; ii) a magnetic code (2) made of a magnetic composition comprising pigment particles; and iii) a non-metallized substrate, wherein the magnetic code has a color matching the color impression of the optically variable layer at one viewing angle and wherein the optically variable layer and the magnetic code are jointly visible from one side of the security thread or stripe.
