ABSTRACT:
Holograms are produced by exposing a film-like sensitive member composed of polyvinylcarbazole or its derivatives containing an iodine compound to an interference pattern of laser, swelling the sensitive member thus exposed in a first solvent and simultaneously eluting most of the iodine compound, if desired, the iodine compound may be eluted before this swelling treatment, and then shrinking the swollen sensitive member in a second solvent.
