Abstract
A multilayer holographic film includes a first layer and an embossed layer on at least one side of the first layer and having a micro-embossed holographic image therein. The embossed layer is thinner than the first layer and has a lower embossing temperature than the first layer. The hologram-receiving layer with a micro-embossed holographic image embossed therein is adapted to receive a metal layer thereon, if desired, and the layer includes a cycloolefin copolymer as the primary polymer component.
