<p>A holographic recording medium comprises (a) an acid generator capable of generating an acid upon exposure to actinic radiation; and (b) a polymer comprising a plurality of high refractive index moieties, a plurality of low refractive index moieties, and a plurality of acid-sensitive linking groups connecting the high and low refractive index moieties. When an interference pattern is formed within this medium, in the light areas of this interference pattern acid is generated by the acid generator and cleaves the acid-sensitive linking groups, thereby causing separation of either the high or the low refractive index moieties from the polymer, and formation of a volume hologram within the medium.</p> |
