ABSTRACT:
This invention pertains to an improved technique of introducing an added insulative layer between the thermoplastic layer and the photoconductive layer of the thermoplastic photoconductive holographic recording medium. The added layer (pure PVK) is electrically insulating at temperatures used for thermal development to prevent decaying charge contrast during hologram development.
