A process for producing an optical security feature as well as a security element and a security document

The invention relates to a method for producing an optical security feature (3), the method comprising the steps of: forming a first electrically conductive coating layer (17a) on a first surface (6a) of a dielectric substrate (14), wherein the first conductive layer of lacquer ( 17a) has one or more first color agent and / or a first relief structure is shaped into at least one surface of the first electrically conductive coating layer (17a) electrodeposition of a first metal layer (18a) on at least one partial area of ​​the side opposite to the dielectric substrate surface of the first electrically conductive lacquer layer (17a) using the first electrically conductive coating layer (17a) as a cathode or anode in the electrodeposition, and a security element (2) and a security document (1).
