Abstract
The invention provides a hologram transfer foil () comprising, that includes, in order from top to bottom, a substrate (), a volume hologram layer () releasably stacked on substrate () and comprising a volume hologram in a cured resin layer, a first heat seal layer () and a second heat seal layer (). In use, the hologram transfer foil () is applied on the second heat seal layer () side over an application member. The adhesion force of volume hologram layer () to the application member is larger than a material fracture force for the volume hologram layer or the application member, so that the hologram transfer layer can be applied by thermo-compression to the application member. This hologram transfer foil is useful for illegal copying of the hologram layer because when the volume hologram is forcibly peeled from the application, a material fracture of the volume hologram layer or application member occurs. When a colored layer functioning as a back layer is provided, it is possible to obtain a hologram transfer foil which eliminates any adverse influence of a coloring component on the volume hologram layer.
