Abstract
A method for transferring a photopolymer hologram from a curved exposure surface to a curved application surface including the steps of forming a release layer on the exposure surface, forming a photopolymer layer on the release layer, forming a protective layer on the photopolymer layer, recording a hologram in the photopolymer layer, removing the protective layer, attaching the laminar assembly comprised of the exposure substrate, the release layer and the photopolymer layer to the curved application surface of the final substrate with an optical adhesive layer located between the photopolymer layer and the curved application surface, and removing the exposure substrate from the release layer.
