Embossing lacquer for micro-optical security elements |
摘要 |
A highly refractive embossing lacquer for producing micro-optic arrangements which contains at least one binding agent which has at least one radiation-curing compound system having one or more organic compounds. The highly refractive embossing lacquer has at least a portion of the organic compounds of the radiation-curing compound system having molecules with at least one polarizable element, so that a polymeric material with a refractive index of greater than 1.5 is formed upon radiation curing. A security element which is produced with at least one micro-optic authenticity feature is also provided. The micro-optic authenticity features permit the production of security elements that are so thin that they can be easily incorporated into value documents.
