Abstract (en)
[origin: US5728449A] PCT No. PCT/EP93/01891 Sec. 371 Date Feb. 13, 1995 Sec. 102(e) Date Feb. 13, 1995 PCT Filed Jul. 18, 1993 PCT Pub. No. WO94/04367 PCT Pub. Date Mar. 3, 1994An anti-copy film or layer for originals or documents comprises according to the invention transparent film material having a multiplicity of at least partially opaque and possibly reflective areas arranged at distances from one another which are arranged as screens on the film surfaces essentially in horizontal planes, in particular parallel to one another, but offset, so that information on an original lying under this film or layer is masked in an approximately vertical viewing direction and is visible in the direction of a predefined viewing angle. Expedient production methods enable the use of photographic techniques.
