An optically variable security element is provided for safeguarding articles of value. The security element has a feature layer containing, in a common plane, first and second feature regions arranged so as to accurately fit together. The first feature regions contain a first embossing lacquer layer of a first embossing lacquer into which an embossed structure that creates a first optical effect has been embossed. The second feature regions contain a second embossing lacquer layer of a second embossing lacquer into which an embossed structure that creates a second, different optical effect has been embossed. The first and second embossing lacquers have different solidification properties and different optical properties. A production process is provided for such an optically variable security element, and to embossing arrangements comprising a semi-finished security element product and means of impressing an embossed structure.
