Patent ID: 8728685

Claim:
A method of manufacturing an article with a volume holographic image, comprising: exposing a holographic recording medium having a plurality of surfaces, comprising a photochemically active dye and a transparent polymeric binder to a plurality of coherent light sources emitting light at one or more writing wavelengths to which the photochemically active dye is sensitive, thereby forming a holographic image therein formed by photoreacted areas of the photochemically active dye and unreacted areas of the photochemically active dye; and then applying a first light-blocking layer or material with a pressure-sensitive or other adhesive, heat lamination, static charge adhesion, or mechanically affixing to a first surface of the holographic recording medium from which surface the holographic image is viewed, said light blocking layer or material absorbing light over the entire wavelength range to which the photochemically active dye is sensitive and allowing transmission of light in a different wavelength range for viewing the holographic image.
