Abstract

A security element includes a coating of a material which has an optically variable effect, in particular a color-tilt effect, and cutouts which are identifiable in transmitted light. The security element comprises a carrier substrate and a partial layer having cutouts. The partial layer is made of an opaque coating having light-absorbing properties on the side that faces the coating made of the material having an optically variable effect and having a metallic coloration on the side that faces away from the coating made of the material having an optically variable effect. The partial opaque coating consists of a light-absorbing metallic layer.
