Patent ID: 7521154

Claim:
A holographic storage optical article comprising: a matrix formed in situ using one of cationic epoxy polymerization, cationic vinyl ether polymerization, cationic alkenyl ether polymerization, cationic alkyl ether polymerization, cationic ketene acetal polymerization, epoxy-amine step polymerization, epoxy-mercaptan step polymerization, unsaturated ester-amine step polymerization (via Michael addition), unsaturated ester-mercaptan step polymerization (via Michael addition), vinyl-silicon hydride step polymerization (hydrosilylation), isocyanate-hydroxyl step polymerization (urethane formation), isocyanate-amine step polymerization (urea formation), Diels-Alder step polymerization, anionic polymerization of cyanoacrylates and sol-gel reactions to form inorganic or hybrid inorganic/organic networks, comprising functional moieties capable of binding to write components; and write components, wherein the write components can be reacted to reversibly bind to functional moieties pendant upon or within the matrix backbone to form a pattern within the optical article when the holographic storage article is exposed to an interference pattern and wherein the write components are not bonded to the matrix and are able to diffuse through the matrix prior to reversibly binding to the matrix to form the pattern, and the holographic storage optical article is rewriteable and is configured to store holographic data and have holographic data retrieved from the article.
