A method for producing a multi-color - volume hologram and a holographic photopolymer film

摘要

It is a method for producing a multi-color - volume hologram with holographic pixels (12a, 12b, 12c) in a photopolymer layer (10) of a photo polymer film (1) is described, in which, in order to a photochemical interaction between adjacent pixels (12a, 12b, 12c) to suppress, before the exposure of the pixels (12a, 12b, 12c) in a boundary region between each two adjacent pixels (12a, 12b, 12c) a transverse diffusion barrier (14) is incorporated. In addition, a photopolymer film for use in such a method is described, consisting of a carrier film (18), from which a photopolymer layer (10) is applied, the pixels (12a, 12b, 12c) has in three different colors, between each of which a transverse diffusion barrier (14) is provided. The transverse diffusion barrier (14) is suppressed, a diffusion of activated monomers between the adjacent pixels (12a, 12b, 12c).
