A security element includes a transparent film, a first layer and a second layer. The first layer includes a first metal arranged on the transparent film in a first pattern. The second layer includes a second metal being a baser metal than the first metal arranged over the first layer in a second pattern. Each of the first and second patterns is composed of metallic regions and metal-free regions. The metal-free regions of the second pattern overlap with the metal-free regions of the first pattern. The metallic regions of the first pattern overlap with the metal-free regions of the second pattern.

Double metal security element having transparent pattern

A security element has a transparent film, a pattern of transparent and non-transparent regions on a first side of the transparent film, and a pattern of transparent and non-transparent regions on a second side of the transparent film. The pattern on the second side of the transparent film matches or is in register with the pattern on the first side of the transparent film. A color changing layer covers the pattern on at least one side of the first and second sides of the transparent film.
