Security Element with Aligned Magnetic Pigments and Laser Static Motif
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security elements for data carriers, such as value documents, lack a combination of high security against forgery with easy recognizability and verifiability, particularly in visual effects that depend on the viewing angle, which are difficult to reproduce with modern copiers.
Innovation Solution
A security element combining magnetically aligned magnetic pigments for a dynamic motif with a laser-generated static motif, where the static motif serves as a stationary reference point for the dynamic effect, enhancing recognition and security through a three-dimensional appearance and movement effect when tilted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetically aligned effect pigments are used to create viewing-angle-dependent visual effects, then security against forgery is improved, but ease of detection and verification by viewers deteriorates
Solution Approach 1:
The patent combines a dynamic motif created by magnetically aligned effect pigments with a static motif created by laser marking on the same security element. This merging allows the dynamic visual effects to provide forgery protection while the static motif provides a fixed reference for easy verification, resolving the contradiction between security and detectability
Solution Approach 2:
The patent applies different properties to different regions of the security element: the dynamic motif area contains magnetically alignable effect pigments that change appearance with viewing angle, while the static motif area is laser-marked with fixed patterns that serve as reference points. This local differentiation allows each region to fulfill its specific function, improving both security and verification ease
2Reliability
If only dynamic motifs with magnetically aligned pigments are used, then forgery protection is enhanced, but visual recognition and attention-grabbing value deteriorate
Solution Approach 1:
The patent merges a dynamic motif with magnetic effect pigments that exhibits viewing-angle-dependent movement effects with a static motif created by laser marking. The static motif provides a fixed reference point that enhances visual recognition and attention-grabbing value, while the dynamic motif maintains forgery protection capabilities
Solution Approach 2:
The patent creates visual asymmetry by combining a stationary laser-marked motif with a dynamic magnetically aligned motif. This asymmetry in motion behavior (one static, one dynamic) creates a more visually striking and attention-grabbing security element that is easier for viewers to recognize and remember
3Ease of manufacture
If traditional printing methods are used for security motifs, then manufacturing simplicity is maintained, but resistance to reproduction by modern copiers deteriorates
Solution Approach 1:
The patent replaces traditional mechanical printing methods with laser marking technology for creating the static motif. Laser marking provides superior resistance to reproduction by modern copiers while maintaining manufacturing efficiency and simplicity, as the laser can directly write complex patterns without requiring physical printing plates or screens
Solution Approach 2:
The patent changes the manufacturing parameter from traditional printing to laser marking, which offers different technical characteristics including higher precision, better resistance to copying, and the ability to create both static and dynamic motifs on the same security element. This parameter change enhances security while maintaining ease of manufacture

AI summary
The invention relates to a security element (12) for security papers, value documents and other data carriers, comprising at least one colour layer (20) containing magnetically aligned magnetic pigments (44), which form a first motif (22) in the form of patterns, signs or an encoding that exhibits a dynamic movement effect when the security element is tilted. According to the invention, the first, dynamic motif (22) is combined with a second, static motif (28) in the form of patterns, signs or an encoding that is generated by the action of laser radiation and the stationary outline of which, under observation, forms a fixed reference point for the dynamic motif.
