Abstract
A method for producing a security feature for a data medium, includes the steps of: providing a molding means having a molding structure of a representation of the security feature; introducing the representation into a substrate by impressing the molding structure; and arranging a light-diffractive or light-refractive structure on the substrate.

A method for producing a security feature for a data medium, comprising the steps of:
- providing a substrate which is transparent or partially transparent in the visible spectral range;
- providing a molding means which has a molding structure and forms an image presentation of a representation which together with a light-diffractive or light-refractive structure generates an optically variable image;
- introducing the representation into one side of the substrate by impressing the molding structure;
- and
- forming a light-diffractive or light-refractive structure on the opposite side of the substrate.
A security feature for a data medium, having a substrate which is transparent or partially transparent in the visible spectral range and in which a representation has been molded which together with a light-diffractive or light-refractive structure generates an optically variable image, and having a light-diffractive or light-refractive structure formed on the substrate, which structure at least partially covers the representation and interacts with it in order to generate a moving representation when the security feature is tilted.
A lamination sheet for the production of a security feature for a data medium, having a molding structure which is an image presentation of a representation which together with a light-diffractive or light-refractive structure generates an optically variable image.
