Abstract (en)
[origin: US5795643A] PCT No. PCT/EP93/02860 Sec. 371 Date Feb. 13, 1995 Sec. 102(e) Date Feb. 13, 1995 PCT Filed Oct. 16, 1993 PCT Pub. No. WO94/09990 PCT Pub. Date May 11, 1994An anticopying film or layer consists of a film or of a layer of transparent material having a large number of completely or partially nontransparent regions which are arranged distances apart and whose planes are arranged in about the same predetermined position relative to the surfaces of the film or of the layer so that, from a predetermined viewing angle onto the surfaces of the anticopying film, the latter is essentially transparent. The regions consist at least partially of photosensitive material which is converted by the action of radiation into nontransparent or reflecting material, it also being possible to provide, in the transparent plastics material, furrows or grooves in which the photosensitive material is present.
