摘要:
An optical storage medium is provided. The optical storage medium may include a light transmissive layer secured to the surface of a data layer and a curable hard coat layer secured to the surface of the light transmissive layer. The data layer may be read, written to, or both read and written to using a laser having a wavelength of less than about 650 nanometers. A method for securing a curable hard coat layer to a light transmissive layer, securing the light transmissive layer to a data layer and curing the hard coat layer is provided.

摘要:
A method of manufacturing an article for display of a holographic image is described that includes thermally fusing a holographic recording medium containing a photochemically active dye dispersed in a transparent thermoplastic polymer binder to another layer or material; and then exposing the holographic film to intersecting beams of coherent light to form a holographic image therein formed by photoreacted areas of the photochemically active dye and unreacted areas of the photochemically active dye.
