摘要:
Security threads or stripes include a substrate and i) a first optically variable layer imparting a first different color impression at different viewing angles, ii) a second optically variable layer imparting a second different color impression at different viewing angles, iii) a first color constant layer having a color matching the color impression of the first or second optically variable layer at a first viewing angle, iv) a second color constant layer having a color matching the color impression of the first or second optically variable layer at a second viewing angle, and v) one or more material-free regions, wherein the first optically variable layer, the second optically variable layer, the first color constant layer, the second color constant layer and the one or more material-free regions are jointly visible from one side of the security thread or stripe.
