PRODUCTION PROCESS OF PHOTOPOLYMER FOR HOLOGRAM RECORDING USING PHOTOREACTIVE HIGH MOLECULAR BINDER IMPROVING STABILITY AND DIFFRACTION EFFICIENCY

摘要

Provided is a production process of photopolymer for hologram recording using a photoreactive high molecular binder which induces photopolymerization of a monomer and a high molecular binder in scope of reinforcing interference so that it possibly produces hologram improved diffraction efficiency. The hologram is materialized by using the photopolymer with the high molecular binder represented by formula 1 and 2 where all molecular units are possibly located at X and polymerized by radicals generated from photoinitiator, in which the high molecular binder includes hydroxyl radicals to react halogen acid like vinyl, acrylate, cellulose, cellulose ester or so on for forming ester combination or to react similar alcohol radicals or other reactive groups for forming ether, ester, urethane or so on.
