    摘要: An optically variable security thread or stripe (T) is provided which could be incorporated into or onto security documents. The security thread or stripe comprises: a) an optically variable layer (1), b) a color constant layer (2) having a color matching the color impression of the optically variable layer at a viewing angle, c) a holographic metallic layer (3) and d) a substrate (4), wherein the optically variable layer, the color constant layer and the holographic metallic layer are at least partially jointly visible from the side of the security thread or stripe comprising the optically variable layer and/or the color constant layer.
