摘要: In the field of protection of value documents and value commercial goods, the present disclosure relates to the field of security threads or stripes to be incorporated into or onto security documents, and security documents having security threads or stripes. The security threads or stripes include i) first optically variable layer imparting a first different color impression at different viewing angles, ii) second optically variable layer imparting a second different color impression at different viewing angles, iii) first color constant layer having a color matching color impression of the first or second optically variable layer at a first viewing angle, iv) second color constant layer having a color matching color impression of the first or second optically variable layer at a second viewing angle, and v) a substrate. The layers are jointly visible from one side of the security thread or stripe.
