A multilayer holographic film including a core layer and a hologram-receiving layer having a lower melting point than said core layer on at least one side of the core layer for including an embossed, holographic image therein and being adapted to receive a metal layer thereon, said hologram-receiving layer(s) include(s) a butene-propylene random copolymer having a melting point in the range of between about 125° C. and about 145° C. and blends thereof; a metallocene catalyzed, isotactic C2/C3 random copolymer with a C2 content of at least about 2% having a melting point in the range of between about 120° C. and about 140° C. and blends thereof or a high density polyethylene homopolymer having a melting point in the range of between about 120° C. and about 130° C. and blends thereof. |
