  • Publication number: 20250146936
    Abstract: A method for generating an at least partial fluorescent property in a material is provided. The method comprises providing the material, providing a laser, arranging the material in a beam path of the laser such that the laser can selectively section wise irradiate the material, and at least section wise irradiating a surface of the material with the laser. The at least sectionwise irradiating of the surface of the material with the laser is performed until visible traces of smoke are formed on the irradiated areas of the surface of the material, whereby a fluorescent property is generated in the irradiated areas.

  • Publication number: 20250033265
    Abstract: A method for producing a film having a security feature for a card-shaped data carrier includes: providing at least one film material having a base color; providing at least one coloring agent; introducing the film material into an extruder of an extrusion apparatus; heating the film material to form a melt; separately heating the coloring agent to form a flowable color; extruding the melt through a nozzle outlet gap of the extrusion apparatus; feeding the flowable color to the extruded melt to form a bead-like mixture; mixing of the flowable color and the extruded melt within the bead-like mixture to form a film. The extruded melt and the flowable color have different material properties so that they do not mix homogeneously, whereby a randomized multi-coloring is visible in plan view of the film. A film and a card-shaped data carrier are associated with aspects of the method.
