Abstract: In the production of an anticopy film serving for covering documents against copying, opaque, strip-like coverings are applied by printing to the individual layers of a transparent, multilayer film in a mutually offset arrangement in such a way that the film appears opaque in the plan view, but transparent in an inclined viewing direction. To this end, a film web is printed with the coverings in sections corresponding to the layers, and the sections are subsequently folded over to give the layers.

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.

Abstract: The magnetic recording medium consists essentially of a polymeric substrate, a coherent, magnetic thin metal film applied to the surface of the substrate by a PVD method and, if required, a protective layer formed on the thin metal film. In order to achieve a large residual induction component in the plane of the film, in particular high residual induction in the transverse direction, the thin metal film contains a noble gas or noble gas mixture, preferably argon. During the coating of the polymeric substrate with the magnetic metal or with the magnetic alloy, the noble gas is fed directly and preferably tangentially to the substrate surface at a specific noble gas flow of from 1.0.multidot.10.sup.4 to 6.0.multidot.10.sup.4. In the plane of the thin metal film, the ratio of residual induction in the longitudinal direction to that in the transverse direction is from about 0.9 to about 1.8.
