<p>A multilayer holographic film including a core layer and a hologram-receivin g 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 poi nt 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 homopolyme r having a melting point in the range of between about 120~C and about 135~C a nd blends thereof.</p> |
