HOLOGRAPHIC RECORDING MEDIUM AND METHOD OF MAKING HOLOGRAPHIC RECORDING MEDIUM

摘要

Articles for recording a hologram are described. The articles include a holographic recording medium having a transparent polymeric binder and a photoreactive dye dispersed therein. The articles also include a first compound, dispersed in the holographic recording medium or disposed over a first surface of the holographic recording medium from which surface the hologram is viewed, that is transparent to light in the wavelength range to which the photoreactive dye is sensitive and which is capable of being converted to a converted compound that is opaque to light in the wavelength range to which the photoreactive dye is sensitive and transparent to light in a different wavelength range for viewing the hologram.
