A transfer film for holographic images is a multilayer structure including a core and at least one outer layer having a sufficient thickness for receiving a holographic image impressed into it. The outer layer is thinner than the core layer and is a propylene/ethylene random copolymer having a DSC melting point in excess of 120 °C. and less than 143 °C. The outer layer further includes an antistatic/release additive therein for permitting multiple releases of a metallized layer initially applied to the outer layer having the holographic image impressed into it, onto a surface of another substrate.
L'invention concerne un film de transfert pour images holographiques, dont la structure multicouche comprend une partie centrale et une couche extérieure au moins ayant une épaisseur suffisante pour recevoir l'impression d'une image holographique. La couche extérieure, qui est plus mince que la couche centrale, est constituée d'un copolymère aléatoire propylène/éthylène ayant un point de fusion DSC supérieur à 120 DEG C et inférieur à 143 DEG C. La couche extérieure renferme également un additif antistatique/anti-adhésif destiné à permettre plusieurs transferts d'une couche métallisée initialement appliquée sur la couche extérieure au niveau de laquelle l'image holographique est imprimée, sur la surface d'un autre substrat.
