Abstract
A major object of the present invention is to provide a volume hologram transfer foil that gives a volume hologram laminate higher in antiforgery function. The present invention achieves the object by providing a volume hologram transfer foil comprising: a substrate, a volume hologram layer carrying a recorded volume hologram that is formed on the substrate, and an image forming layer carrying a formed image and a heat seal layer containing a thermoplastic resin that are formed on the volume hologram layer, and comprising no reflective layer having a function to reflect light.
Claims4
A volume hologram transfer foil, comprising:
- a substrate;
- a volume hologram layer carrying a recorded volume hologram that is formed on the substrate;
- and
- an image forming layer carrying a formed image and a heat seal layer containing a thermoplastic resin that are formed on the volume hologram layer,
- wherein the volume hologram transfer foil comprises no reflective layer having a function to reflect light;
- a peelable over protection layer is formed between the volume hologram layer and the substrate;
- the image forming layer is formed partially;
- the image forming layer is an optically-variable-image forming layer carrying an image formed by an optically variable material changing its color by viewing angle;
- and the optically-variable-image forming layer can develop a color identical with a color of the volume hologram image recorded in the volume hologram layer when seen from a particular angle.
