Abstract: A process for producing an optical security component including stamping a transparent film with a matrix having a first type of zone whose surface state is matte, and a second type of zone whose surface state has cuttings/slits for forming a diffraction network; depositing a layer of dielectric material with a high optical index on an entire surface, under a vacuum, on the film; partial metallization of the film by depositing a layer of metal on only part of the zones of each types whereas the other part remains transparent; and applying an adhesion layer.
