Method for producing a volume hologram film having security elements formed as transfer sections

Abstract The invention relates to a method for forming a volume hologram film (1f) having security elements (1), which are formed as transfer sections of the volume hologram film (1f), wherein the volume hologram film (1f) has n volume hologram layers (13) arranged one over the other. The production of the volume hologram film (1f) is performed in a roll-to-roll method having the following steps: a) providing a carrier film (11) from a supply roll (31); b) applying an i-th photopolymer layer (12) to the carrier film (11); c) forming an i-th volume hologram in the photopolymer layer (12); d) forming an i-th volume hologram layer (13i) by curing the i-th photopolymer layer (12); e) repeating the process steps b) to e) n-1 times; f) applying an adhesive layer (16) to the background layer (15); g) winding the volume hologram film (1f) onto a winding roll (32).
