    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.

    摘要： The invention relates to the field of non-spherical magnetic or magnetisable pigment particles and coating compositions comprising those pigment particles for producing optical effect layers (OEL) wherein the magnetic or magnetisable pigment particles are magnetically oriented. In particular, the present invention provides uses of said optical effect layers (OEL) layers as anti-counterfeit means on security documents or security articles. In particular, it relates to the field of non-spherical magnetic or magnetisable pigment particles comprising a magnetic metal selected from the group consisting of cobalt, iron, gadolinium and nickel; a magnetic alloy of iron, manganese, cobalt, nickel, or a mixture of two or more thereof; a magnetic oxide of chromium, manganese, cobalt, iron, nickel or a mixture of two or more thereof; or a mixture of two or more thereof, and having a d50 value higher than 6 μm and lower than 13 μm, their uses in coating compositions comprising a binder material for producing an optical effect layer (OEL), OEL obtained thereof and processes for producing said OEL.
