Abstract (en)
[origin: WO2016008553A1] The invention relates to a security element with manipulation detection, in particular a security label or a transferable element, having the following layers: a) a first layer which is an embossed support substrate or a support substrate (1) with a coating layer (6) that has an optically active structure (7) or a first liquid crystal layer, b) a second layer which is a liquid crystal layer (3), c) a light-absorbing layer (4), and d) an adhesive layer (5), wherein the adhesion between the layers a. and b. is lower than the adhesion between the layers b., c., and d., and the security element has a color shift effect.
