Patent ID: 8609300

Claim:
A method of manufacturing an article for display of a volume holographic image, comprising: co-extruding a layer having a thickness of 1 μm to 2000 μm of a holographic recording medium comprising a photochemically active dye dispersed in and not chemically attached to a transparent thermoplastic polymer binder with a thermoplastic layer to thermally fuse the holographic recording medium with the thermoplastic layer thereby forming said article comprising a holographic recording layer having a thickness of 1 μm to 2000 μm thermally fused to the thermoplastic layer; and then exposing the holographic recording layer having a thickness of 1 μm to 2000 μm to intersecting beams of coherent light to form a volume holographic image therein formed by photoreacted areas of the photochemically active dye and unreacted areas of the photochemically active dye.
