Patent No. EP4069522 (titled "Decorative Foil, Method For Producing A Decorative Foil And Method For Decorating A Target Substrate") was filed by Leonhard Kurz Stiftung on Nov 20, 2020. The application was issued on Dec 4, 2024.
Decorative film for security documents, comprising a carrier film, a lacquer layer, and an adhesive layer, wherein the lacquer layer comprises at least one metallic layer and/or at least one dielectric layer, and the adhesive layer is designed to tear at the outer edge of the lacquer layer, thereby preventing undefined cracks in the paint layer. The film is produced by applying the lacquer layer to the carrier film and then applying the adhesive layer, which is cured using UV radiation. The film is then applied to a target substrate using a pressing process, resulting in a high-quality, crack-free decoration.
