Abstract (en)

A security fibre in the form of a small strip of paper (1; 51; 52) is suitable for incorporation into a paper product, for use in counterfeit protection. In example embodiments of the invention, the security fibre (1; 51; 52) comprises (i) a central region (2) made up of a plurality of different colours (21; 22; 23; 24), and (ii) a sacrificial margin (3; 31; 32; 33; 34) adjacent to the coloured region (2). The margin (3; 31; 32; 33; 34) includes a varnish. In example embodiments of the invention, the varnish alters the physical properties of the margin, for example by emitting light when illuminated with infra-red light, or by emitting light as a result of the anti-Stokes effect.
